Modify the attached c++ file , so that the program finds the number of times the isPalindrome function is called.
(Hint: Use a global variable and increment it every time the function is called.)
![#include <iostream>
#include <string>
using namespace std;

if (s.size() <= 1) // Base case
return true;
else if (s[0] != s[s.size() - 1]) // Base case
return false;
else
return ispalindrome (s.substr(1, s.size() -2));
}
int main()
{
}
cout << "Enter a string: ";

getline(cin, s);
if (isPalindrome(s))
cout << s << " is a palindrome << endl;
else
cout << s << " is not a palindrome" << endl;
