 C++ Confusion Buster: Your Easy Guide to C++ !

// Reverse a string

// Shyam Sunder Kanth

// Insta : still_23.6_8

#include<iostream>

#include<algorithm>

#include<stack>

using namespace std;

int main()

{

    string str = "Hello";

    // Way-1 : Using function

    reverse(str.begin(), str.end());

    // Way-2 : Two pointer method

    for(int i =0,j=str.length()-1;i<=j;i++,j--){

        swap(str[i],str[j]);

    }

    // Way -3

    // Using stack

    stack<char> st;

    for(int i=0;i<str.length();i++){

        st.push(str[i]);

    }

    string res = "";

    while(!st.empty()){

        char ch = st.top();

        res = res + ch;

        st.pop();

    }

    cout<<res;

    return 0;

}
