Reverse String C++ Solution

    R
    class Solution {
    public:
        string reverseString(string s) 
        {
            int n = s.length();    
            for(int i = 0; i < n/2; i++)
                swap(s[i], s[n - i - 1]);
            return s;
        }
    };
    

    We use half the size of the string to reduce the runtime.
