reverse a string

You are given a string s. You need to reverse the string.

Example 1:

Input:
s = Geeks
Output: skeeG

 #include<bits/stdc++.h>

using namespace std;

string reverseWord(string str);

int main() {

int t;

cin>>t;

while(t--)

{

string s;

cin >> s;

cout << reverseWord(s) << endl;

}

return 0;

}

// } Driver Code Ends

//User function Template for C++

string reverseWord(string str){

    int len = str.length()-1;

    int i=0;

    while(i<len)

    {

        char c = str[i];

        str[i] = str[len];

        str[len] = c;

        i++;

        len--;

    }

    

  return str;

}
