    When I first learned ruby, it happened that the algorithm teacher encouraged me to write algorithms in unfamiliar languages. I’ll use ruby~~Ruby is really powerful. Many intuitive methods can be used….. Worship infinity…. During this period, I encountered the error of invalid multibyte char (us-ascii). The solution is to add a #encoding: UTF-8 at the […]

      Title Link   First, sort the input numbers, and use quick sort from small to large. After shooting the sequence, go to find the longest sequence. The search process can add a currently found longest sequence to the loop to reduce the time complexity.   #include<stdio.h> Int QW (long long int Z [], long […]

  • Quicksort algorithm in C + +

    Time:2020-12-28

    This example for you to share the C + + quick sort algorithm, for your reference, the specific content is as follows 1、 The basic idea is as follows: Through one-step sorting, the data to be sorted is divided into two independent parts. All the data of one part is smaller than that of the […]

  • The principle of quick sort algorithm and its implementation in go language

    Time:2020-7-9

    Quick sort is an important sorting algorithm based on divide and conquer technology. Unlike merge sort, which divides elements according to their positions in the array, quick sort divides elements by their values. Specifically, it rearranges the elements in a given array to get a quick sort partition. In a partition, all elements before s […]

  • C Language Simply Realizes Quick Sorting

    Time:2019-6-29

    Quick sorting is a kind of unstable sorting. Its time complexity is O (n. lgn), the worst case is O (n2), and the space complexity is O (n. lgn).This sort method is an improvement on bubble sort. It uses divide-and-conquer mode to divide one-time sorted data into two separate parts, in which each value of […]
