Palindrome String

Minimum characters to make string palindrome

string s;
    int len=0,i=1;
    cin>>s;
    int n=s.size();
    vector<int> LPS(n);
    LPS[0]=0;
    while(i<n)
    {
        if(s[i]==s[len]) LPS[i++]=++len;
        else
        {
            if(len==0) LPS[i++]=0;
            else len=LPS[len-1];
        }
    }

Check if a string is a palindrome

int length = myString.Length;
for (int i = 0; i < length / 2; i++)
{
    if (myString[i] != myString[length - i - 1])
        return false;
}
return true;
