Reverse String

 

Write a function that takes a string as input and returns the string reversed.

 

Example:

Given s = "hello", return "olleh".

 

/*class Solution

{

public:

    string reverseString(string s)

    {

        int i = 0;

        int j = s.size() - 1;

        while(i<j)

        {

            swap(s[i++],s[j--]);

        }

       

        return s;

    }

};*/

class Solution

{

public:

    string reverseString(string s)

    {

        reverse(s.begin(), s.end());

        return s;

    }

};
