CODE EXAMPLE FOR CPP

reverse an array in c++ stl

//Reverse an array using C++ STL
#include <algorithm>  //Header file for reverse method

 int arr[] = { 1, 2, 3, 4, 5 };
 int n = sizeof(arr) / sizeof(arr[0]);  //Size of array
 reverse(arr, arr + n);
 //Now array looks like = { 5, 4, 3, 2, 1 }
 //The time complexity is O(n)
