Quick Sort Merge Sort Pdf Computer Programming Algorithms And Like quicksort, merge sort is a divide and conquer algorithm. it divides input array in two halves, calls itself for the two halves and then merges the two sorted halves. Difference between merge sort and insertion sort: in insertion sort the worst case: o (n2), average case: o (n2), and best case: o (n). in insertion sort only takes o (1) auxiliary space complexity. it sorts the entire array just by using an extra variable. datasets: merge sort is preferred for huge data sets.

Quick Sort Merge Sort We will discuss four comparison sort algorithms: selection sort and insertion sort have worst case time o (n2). quick sort is also o (n2) in the worst case, but its expected time is o (n log n). merge sort is o (n log n) in the worst case. the idea behind selection sort is: find the smallest value in a; put it in a [0]. In c , you can use std::sort(most likely a hybrid sorting algorithm: introsort), std::stable sort(most likely merge sort), or std::partial sort(most likely binary heap) in stl algorithm.
