Try for a recursive algorithm: 1. if the string has length <=1, it's a palindrome. 2. else, the string is a palindrome if its initial and ending characters are equal, and the inner characters form a palindrome string.

This code should reverse the stirng #include <iostream> using namespace std; int main() { string s; char c; int l; s="sololearn"; l=s.size(); for(int i=0;i<s.size()/2+1;i++){ c=s[i]; s[i]=s[l-i-1]; s[l-i-1]=c; } cout<<s; } the output is "nraelolos" and then you compare the strings
