typedefstd::pair<int,int>pair; intmain() { std::vector<pair>v={{1,2},{6,4},{3,4},{6,1}}; // sorts pairs in increasing order of their first value std::sort(v.begin(),v.end()); // sorts pairs in decreasing order of their first value ...
Sorts the elements in the range[first,last)in non-descending order. The order of equal elements is not guaranteed to be preserved. 1)Elements aresortedwith respect tooperator<(until C++20)std::less{}(since C++20). 3)Elements are sorted with respect tocomp. ...
When a large amount of data is to be dealt with, the most efficient way is to store it in an optimized manner, where it is arranged in either ascending or descending format. There are many sorting techniques like Merge Sort, Quick Sort, Bubble Sort, etc. In this article, we will ...

function object to thestd::sortalgorithm. In this case, we utilize a lambda expression to form a function object and pass it as the third argument of thesortfunction call. Note that this essentially is the method to define any custom comparison routine for the elements of the pair. ...
If we have an array of strings or integers, we can easily sort them using the sort() function in JavaScript. For example, let’s sort an array of strings alphabetically using the sort() function. See the code below.var a = ['banana', 'apple', 'orange']; var m = a.sort(); ...
Bubble sort is a basic algorithm for arranging a string of numbers or other elements in the correct order. The method works by examining each set of adjacent elements in the string, from left to right, switching their positions if they are out of order Bubble_sort.cpp #include <iostream> ...
This relation works in both directions by allow the value to also act as a key to key, e.g. a pair (a,b) thus provides a coupling between 'a' and 'b' so that 'b' can be found when 'a' is used as a key and 'a' can be found when 'b' is used as a key. type BidiMap...
