void ChangeCase(char str[], int n)
{
    
 
    
    for (int i = 0; i < n; i++) {
        if (str[i] >= 'a' && str[i] <= 'z')
            
            str[i] = str[i] - 32;
        else if (str[i] >= 'A' && str[i] <= 'Z')
            
            str[i] = str[i] + 32;
    }

int main(){
	cout<<"Enter the size of the array:\n";
	int n;
	cin>>n;
	char letters[n];
	cout<<"Enter the string\n";
	cin>>letters;
	ChangeCase(letters,n);
	cout<<letters<<endl;
}
