Quick Sort Algorithm
Given an array with n elements, we want to rearrange them in ascending order. In this paper, we introduce Quick Sort, a divide-and-conquer algorithm to sort an N element array. We evaluate the O(NlogN) time complexity in best case and O(N) in worst case theoretically. We also introduce a way to approach the best case.
متن کاملQuick Sort on SCMPDS
This means we cannot justify the correctness of the “Partition” subroutine by the Hoare’s axiom on program verification. This article is organized as follows. First, we present several fundamental properties of “while” program and finite sequence. Second, we define the “Partition” subroutine on SCMPDS, the task of which is to split a sequence into a smaller and a larger subsequence. The definit...

متن کاملDo hypercubes sort faster than tree machines?
SUMMARY We develop a balanced, parallel quicksort algorithm for a hypercube and compare it with a similar algorithm for a binary tree machine. The performance of the hypercube algorithm is measured on a Computing Surface.
متن کاملPerformance Analysis of Merge Sort and Quick Sort: MQSORT
Sorting is considered as a fundamental operation in computer science as it is used as an intermediate step in many operations. Sorting refers to the operation of arranging data in some given order such as increasing or decreasing, with numerical data, or alphabetically, with character data. An algorithm is any well-defined procedure or set of instructions, that takes some input in the form of s...
