#include<iostream>

using namespace std;

// Function to convert characters

for (int i=0; i<ln; i++)

{

if (str[i]>='a' && str[i]<='z')

//Convert lowercase to uppercase

str[i] = str[i] - 32;

else if(str[i]>='A' && str[i]<='Z')

//Convert uppercase to lowercase

str[i] = str[i] + 32;

}

}

cout << str;
