Can quicksort be implemented in C without stack and recursion?

WebMost of the steps in merge sort are simple. You can check for the base case easily. Finding the midpoint q q q q in the divide step is also really easy. You have to make two recursive calls in the conquer step. It's the combine step, where you have to merge two sorted subarrays, where the real work happens.

WebNow we have to figure out the running time of two recursive calls on n/2 n/2 elements. Each of these two recursive calls takes twice of the running time of mergeSort on an (n/4) (n/4) -element subarray (because we have to halve n/2 n/2) plus cn/2 cn/2 to merge. WebMay 4, 2016 · When you execute quicksort or mergesort, you are recursively breaking down your array into smaller pieces that do not overlap. You never operate over the same elements of the original array twice during any given level of the recursion. This means there is no opportunity to re-use previous calculations. WebJan 10, 2024 · 1) Partition process is the same in both recursive and iterative. The same techniques to choose optimal pivot can also be applied to the iterative version. 2) To reduce the stack size, first push the indexes of smaller half. 3) Use insertion sort when the size reduces below an experimentally calculated threshold. ctk 450 casio
