Row major and column major in 2 d
Row major and column major in 2 dnikhilarora2211 This document discusses row-major and column-major ordering for representing 2D arrays in memory. In row-major order, elements are arranged sequentially row by row, with the first row occupying the first memory locations. Column-major order arranges elements column by column. Formulas are provided to calculate the memory location of a given element based on its indices, the array base address, element size, number of rows, and whether the array uses row-major or column-major ordering. An example calculates the location of element A[3,2] for both a row-major and column-major 3x4 integer array.
Merge sort
Merge sortMd. Rakib Trofder Merge sort is a sorting algorithm that works by dividing an array into two halves, recursively sorting the halves, and then merging the sorted halves into a single sorted array. The document provides details on how merge sort works, including pseudocode for the main, merge sort, and merging functions. It analyzes the time complexity of merge sort as O(n log n), making it more efficient than other basic sorts with O(n^2) time complexity like bubble, selection, and insertion sort.
Sorting algorithms
Sorting algorithmsMaher Alshammari The document discusses several sorting algorithms including selection sort, insertion sort, bubble sort, merge sort, and quick sort. It provides details on how each algorithm works including pseudocode implementations and analyses of their time complexities. Selection sort, insertion sort and bubble sort have a worst-case time complexity of O(n^2) while merge sort divides the list into halves and merges in O(n log n) time, making it more efficient for large lists.
Quick sort
Quick sortamar kakde Quicksort is a divide and conquer algorithm that works by partitioning an array around a pivot value and recursively sorting the sub-partitions. It first chooses a pivot element and partitions the array by placing all elements less than the pivot before it and all elements greater than it after it. It then recursively quicksorts the two partitions. This continues until the individual partitions only contain single elements at which point they are sorted. Quicksort has average case performance of O(n log n) time making it very efficient for large data sets.
3.8 quicksort
3.8 quicksortKrish_ver2 The document discusses quicksort, an efficient sorting algorithm. It begins with a review of insertion sort and merge sort. It then presents the quicksort algorithm, including choosing a pivot, partitioning the array around the pivot, and recursively sorting subarrays. Details are provided on the partition process with examples. Analysis shows quicksort has worst-case time complexity of O(n^2) but expected complexity of O(nlogn) with only O(1) extra memory. Strict proofs are outlined for the worst and expected cases. The document concludes with notes on implementing quicksort in Java for practice.
Data Structure (Queue)
Data Structure (Queue)Adam Mukharil Bachtiar Queue is a first-in first-out (FIFO) data structure where elements can only be added to the rear of the queue and removed from the front of the queue. It has two pointers - a front pointer pointing to the front element and a rear pointer pointing to the rear element. Queues can be implemented using arrays or linked lists. Common queue operations include initialization, checking if empty/full, enqueue to add an element, and dequeue to remove an element. The document then describes how these operations work for queues implemented using arrays, linked lists, and circular arrays. It concludes by providing exercises to implement specific queue tasks.
Insertion sort
Insertion sortMYER301 The document discusses insertion sort, a simple sorting algorithm that builds a sorted output list from an input one element at a time. It is less efficient on large lists than more advanced algorithms. Insertion sort iterates through the input, at each step removing an element and inserting it into the correct position in the sorted output list. The best case for insertion sort is an already sorted array, while the worst is a reverse sorted array.
Asymptotic notations
Asymptotic notationsEhtisham Ali 1. Asymptotic notation such as Big-O, Omega, and Theta are used to describe the running time of algorithms as the input size n approaches infinity, rather than giving the exact running time.
2. Big-O notation gives an upper bound and describes worst-case running time, Omega notation gives a lower bound and describes best-case running time, and Theta notation gives a tight bound where the worst and best cases are equal up to a constant.
3. Common examples of asymptotic running times include O(1) for constant time, O(log n) for logarithmic time, O(n) for linear time, and O(n^2) for quadratic time.

Quick sort
Quick sortAfaq Mansoor Khan Quicksort is a divide and conquer algorithm that works by partitioning an array around a pivot value and recursively sorting the subarrays. It first selects a pivot element and partitions the array by moving all elements less than the pivot before it and greater elements after it. The subarrays are then recursively sorted through this process. When implemented efficiently with an in-place partition, quicksort is one of the fastest sorting algorithms in practice, with average case performance of O(n log n) time but worst case of O(n^2) time.
Selection sort
Selection sortsmlagustin Selection sort is a sorting algorithm that finds the smallest element in an unsorted list and swaps it with the first element, then finds the next smallest element and swaps it with the second element, continuing in this way until the list is fully sorted. It works by iterating through the list, finding the minimum element, and swapping it into its correct place at each step.
Graph traversals in Data Structures
Graph traversals in Data StructuresAnandhasilambarasan D Graph traversal techniques are used to search vertices in a graph and determine the order to visit vertices. There are two main techniques: breadth-first search (BFS) and depth-first search (DFS). BFS uses a queue and visits the nearest vertices first, producing a spanning tree. DFS uses a stack and visits vertices by going as deep as possible first, also producing a spanning tree. Both techniques involve marking visited vertices to avoid loops.
Linear and Binary search
Linear and Binary searchNisha Soms Binary search provides an efficient O(log n) solution for searching a sorted list. It works by repeatedly dividing the search space in half and focusing on only one subdivision, based on comparing the search key to the middle element. This recursively narrows down possible locations until the key is found or the entire list has been searched. Binary search mimics traversing a binary search tree built from the sorted list, with divide-and-conquer reducing the search space at each step.
Quicksort Presentation
Quicksort Presentationirdginfo Quick Sort is a recursive divide and conquer sorting algorithm that works by partitioning a list around a pivot value and recursively sorting the sublists. It has average case performance of O(n log n) time. The algorithm involves picking a pivot element, partitioning the list based on element values relative to the pivot, and recursively sorting the sublists until the entire list is sorted. An example using Hoare's partition scheme is provided to demonstrate the partitioning and swapping steps.
Multiplication algorithm
Multiplication algorithmGaurav Subham Booth's multiplication algorithm multiplies two signed binary numbers in two's complement notation. It was invented by Andrew Donald Booth in 1950. The algorithm inspects two bits of the multiplier at a time, and either adds, subtracts, or leaves unchanged the partial product depending on whether the bits are 10, 01, or the same. It shifts the partial product and multiplier arithmeticly to the right after each step to inspect the next bits.
Quick sort Algorithm Discussion And Analysis
Quick sort Algorithm Discussion And AnalysisSNJ Chaudhary Quicksort is a divide-and-conquer algorithm that works by partitioning an array around a pivot element and recursively sorting the subarrays. In the average case, it has an efficiency of Θ(n log n) time as the partitioning typically divides the array into balanced subproblems. However, in the worst case of an already sorted array, it can be Θ(n^2) time due to highly unbalanced partitioning. Randomizing the choice of pivot helps avoid worst-case scenarios and achieve average-case efficiency in practice, making quicksort very efficient and commonly used.

Three Address code 
Three Address code Pooja Dixit The document discusses three address code, which is an intermediate code used by optimizing compilers. Three address code breaks expressions down into separate instructions that use at most three operands. Each instruction performs an assignment or binary operation on the operands. The code is implemented using quadruple, triple, or indirect triple representations. Quadruple representation stores each instruction in four fields for the operator, two operands, and result. Triple avoids temporaries by making two instructions. Indirect triple uses pointers to freely reorder subexpressions.

Turing machine-TOC
Turing machine-TOCMaulik Togadiya The document discusses Turing machines. It begins by introducing Alan Turing as the father of the Turing machine model. A Turing machine is a general model of a CPU that can manipulate data through a finite set of states and symbols. It consists of a tape divided into cells that can be read from and written to by a tape head. The tape head moves left and right across the cells. The document then provides examples of constructing Turing machines to accept specific languages, such as the language "aba" and checking for palindromes of even length strings. Transition tables are used to represent the state transitions of the Turing machines.
Asymptotic notation
Asymptotic notationDr Shashikant Athawale This document discusses asymptotic notations that are used to characterize an algorithm's efficiency. It introduces Big-Oh, Big-Omega, and Theta notations. Big-Oh gives an upper bound on running time. Big-Omega gives a lower bound. Theta gives both upper and lower bounds, representing an algorithm's exact running time. Examples are provided for each notation. Time complexity is also introduced, which describes how the time to solve a problem changes with problem size. Worst-case time analysis provides an upper bound on runtime.
Divide and conquer
Divide and conquerDr Shashikant Athawale The document discusses divide and conquer algorithms. It describes divide and conquer as a design strategy that involves dividing a problem into smaller subproblems, solving the subproblems recursively, and combining the solutions. It provides examples of divide and conquer algorithms like merge sort, quicksort, and binary search. Merge sort works by recursively sorting halves of an array until it is fully sorted. Quicksort selects a pivot element and partitions the array into subarrays of smaller and larger elements, recursively sorting the subarrays. Binary search recursively searches half-intervals of a sorted array to find a target value.

Access pattern of tags
Access pattern of tagsHarish Chetty The project is based on detecting frequent patterns on a web-server by using the server log. It generates multi-level statistics based on Apriori algorithm with each level determined by Pattern length.
Currently this is a dynamic programming form of Apriori where we have implemented the rule that to be a frequent pattern at a level k (i.e patter of size k), one of the elements from its powerset of size (k-1) must be frequent. This helps in improving the efficiency to less than quadratic time on average.

YSPH VMOC Special Report - Measles Outbreak Southwest US 5-3-2025.pptx
YSPH VMOC Special Report - Measles Outbreak Southwest US 5-3-2025.pptxYale School of Public Health - The Virtual Medical Operations Center (VMOC) A measles outbreak originating in West Texas has been linked to confirmed cases in New Mexico, with additional cases reported in Oklahoma and Kansas. The current case count is 817 from Texas, New Mexico, Oklahoma, and Kansas. 97 individuals have required hospitalization, and 3 deaths, 2 children in Texas and one adult in New Mexico. These fatalities mark the first measles-related deaths in the United States since 2015 and the first pediatric measles death since 2003.
The YSPH Virtual Medical Operations Center Briefs (VMOC) were created as a service-learning project by faculty and graduate students at the Yale School of Public Health in response to the 2010 Haiti Earthquake. Each year, the VMOC Briefs are produced by students enrolled in Environmental Health Science Course 581 - Public Health Emergencies: Disaster Planning and Response. These briefs compile diverse information sources – including status reports, maps, news articles, and web content– into a single, easily digestible document that can be widely shared and used interactively. Key features of this report include:
- Comprehensive Overview: Provides situation updates, maps, relevant news, and web resources.
- Accessibility: Designed for easy reading, wide distribution, and interactive use.
- Collaboration: The “unlocked" format enables other responders to share, copy, and adapt seamlessly. The students learn by doing, quickly discovering how and where to find critical information and presenting it in an easily understood manner.

APM Midlands Region April 2025 Sacha Hind Circulated.pdf
APM Midlands Region April 2025 Sacha Hind Circulated.pdfAssociation for Project Management APM event hosted by the Midlands Network on 30 April 2025.
Speaker: Sacha Hind, Senior Programme Manager, Network Rail
With fierce competition in today’s job market, candidates need a lot more than a good CV and interview skills to stand out from the crowd.
Based on her own experience of progressing to a senior project role and leading a team of 35 project professionals, Sacha shared not just how to land that dream role, but how to be successful in it and most importantly, how to enjoy it!
Sacha included her top tips for aspiring leaders – the things you really need to know but people rarely tell you!
We also celebrated our Midlands Regional Network Awards 2025, and presenting the award for Midlands Student of the Year 2025.
This session provided the opportunity for personal reflection on areas attendees are currently focussing on in order to be successful versus what really makes a difference.
Sacha answered some common questions about what it takes to thrive at a senior level in a fast-paced project environment: Do I need a degree? How do I balance work with family and life outside of work? How do I get leadership experience before I become a line manager?
The session was full of practical takeaways and the audience also had the opportunity to get their questions answered on the evening with a live Q&A session.
Attendees hopefully came away feeling more confident, motivated and empowered to progress their careers
