I am pulling a request to add distance function that is in algorithm header file

distance (start-iterator, final position)– It returns the distance of desired position from the first iterator.This function               is very useful while finding the index.

Code(c++):

 // C++ program to demonstrate working of distance()

#include

#include

#include

using namespace std;

 

int main()

{

    // Initializing vector with array values

    int arr[] = {5, 10, 15, 20, 20, 23, 42, 45};

    int n = sizeof(arr)/sizeof(arr[0]);

    vector vect(arr, arr+n);

 

    // Return distance of first to maximum element

    cout << "Distance between first to max element: ";

    cout << distance(vect.begin(),

                     max_element(vect.begin(), vect.end()));

    return 0;

}
