We can sort an array or STL containers like vector, set, map, etc., in C++ using thesort()function. #include<algorithm>#include<iostream>using namespace std;intmain(){intarr[]={1,5,8,9,6,7,3,4,2,0};// array sizeintn=sizeof(arr)/sizeof(arr[0]);vector<int>v{35,67,11,...
intb)const{// Customize the sorting order hereif(fr[a]==fr[b])returna>b;// Sort values in descending orderelsereturnfr[a]<fr[b];// Sort frequencies in ascending order}};// Create a set using the custom sorting criterionset<int,sortCri>nums;...
Is there any way to do this using STL (as i want to be efficient my code needs to sort anout 1000 entries) for eg. let my vector be (1.0,4.1,3.1,2.3) then i want the output vector to be ( 1,4,3,2) // indices of original vector in sorted order ...
So, now let us see how we can sort a vector in C++(ascending order).#include<iostream> #include<vector> #include<algorithm> using namespace std; int main() { //vector initialisation vector<int> vec {5, 4, 3, 2, 1}; cout<<"Before sorting vector : "; for(auto i=vec.begin();...
In this post, I would like to give an entry level example of how you can use NVIDIA CUDA technology to achieve better performance within C# with minimum possible amount of code. This is a very specific scenario where the main application is in C#, and the sorting algorithm is provided in...

After some research, I found that merge sort's worst case number of comparisons is n * ceil(logn) — 2^(ceil(logn)) + 1 which gives 8 in this case. I couldn't find a better sorting algorithm that would solve the problem — I even tried STL sort which proved to be worse than me...
