Answer 1

Answer:

// C++ program to reverse a string using recursion

#include <bits/stdc++.h>

using namespace std;

/* Function to print reverse of the passed string */

void reverse(string str)

{

if(str.size() == 0)

{

return;

}

reverse(str.substr(1));

cout << str[0];

}

/* Driver program to test above function */
