The article showcase an array to be reversed in descending order using the C++ coding wherein the highest index is swapped to lowest index consequently by traversing the array in the loop. Example Live Demo #include <iostream> #include <algorithm> using namespace std; void reverseArray(int ...
array without modifying the original or underlying array by creating a new sequence of elements in the reversed order. Invoke theEnumerable.Reverse()method to invert the order of an array’s element, which is more convenient and easier to read than any other method or custom reverse algorithm....
Requirement: You can only do in array swap, you cannot create a new array. The way to do it: 1. Reverse whole string to get: ["e","c","i","t","a","r","p","","e","k","a","m","","t","e","f","e","r","p"] 2. Then we reverse each word to get final r...

The only way to sort a primitive array in descending order is first to sort it in ascending order and thenreverse the array in placeas shown here.Since in place reversal is an efficient algorithm and doesn't require extra memory, you can use it sort and reverse large array as well. You...
Alternatively, to reverse the array elements in place without declaring other variables, we can call thestd::reversefunction from the standard library.std::reverseis part of the<algorithm>header and has been part of the standard library since the C++17. The function takesstart/enditerators of th...
