int palindrome(string a) { assert(a.length());//Abort is string empty int val = 1;//default value is true for(int i = 0; i < a.length(); i++)//Can actually restrict i:0-length/2 val *= (a[i]==a[a.length()-1-i]); return val; }

Python implimentation string==string[::-1] Of course your interviewer will ask you to elaborate.
