Here it’s done with std::sort from the header algorithm #include <iostream> #include <string> #include <algorithm> #include <vector> int main(){ std::vector<std::string> nums{ “922003001020293839297830207344987344973074734”, “766352786207892397340783784078348747606208602”, “182823068326283756515117829362376823572395775” }; std::cout << “unsorted: ” << std::endl; for (auto i : nums){ std::cout << i <<…
Sort both of these “simultaneously”. System.Threading.Tasks.Task.Run(() => quick_sort(a1,0,100)); System.Threading.Tasks.Task.Run(() => quick_sort(a2,0,100)); solved How can i sort two integer arrays parallel with quick sort in C#?
Your first implementation worked but had degenerate behavior with specific datasets. The pivot in your original working code was *(last – 1) so the simplest fix would be to swap a random element with *(last – 1). The rest of…
Quick sort is in-place manipulation. Means you will be modifying original array only. No need to create extra arrays. This is answer of your both questions. Try this code void qsort(int* xArray, int xSize) { int lPivot = xArray[xSize-1]; int…
I have fixed your error see below code. static void dog(int i, int b, int c, int array[]) { if (c<array.length-1 && array[i] <= array[c] ) { if (c <(int) array.length-1) { int y = array[i]; array[i] = array[b]; array[b]…
Your code is not right: it does not do a stable partition of the array. Imagine your array is 100, 33, 333, 22, 222, 11 After the stable partitioning around the first element, it should become 33, 22, 11, 100,…
use std::sort from the <algorithm> header you can use a lambda expression as comparison function 4 solved C++: How-to sort 2-d array with qsort? [closed]
The code snippet swaps the values of array[left] and array[right], nothing more. It does so by first memorizing the value of array[left] in a temporary variable temp because it soon gets overridden. After that it overrides the value at array[left]…
You can use Arrays.sort() to sort your array before feeding it, each of the following describe how to achieve one thing you asked for – try to do each on the array (one at a time) before invoking sort(a) To…
Actually I could not find the exact problem in your program, but if you want a program to perform quicksort on an array of elements, this is it: #include<stdio.h> void quicksort(int [10],int,int); int main(){ int x[20],size,i; printf(“Enter size of the…
