    string manipulate

    I am trying to resolve the below string manipulation.
    But code doesn't work as expected. Need help with some inputs.

    Input

    First line of input contains string M, consisting of lowercase English letters. Second line of input contains integer N, consisting of characters to be removed.

    Output

    Print 1 if string is k-drome, 0 otherwise. Here the constraint is 1 <= length of M <= 100



    Code:
    //function to resolve the string
    bool isKdrom(char * M, int N, int k)
    {
    	while (N >=1 && M[0] == M[N-1])
    	{
    		M++; N-=2;
    	}
    
    	if (N <= 1) return true;
    
    	if (k > 0)
    		return isKdrom(M+ 1, N-1, k-1) || isKdrom(M, N-1, k-1);
    
    	return false;
    }

    Your question makes no sense to me.
    What is "k-drome"?
    What do you mean "characters to remove"?
    In what way does it not "work as expected"?

    Below are the comments added inline here.

    What is "k-drome"? A string is k-drome if it can be transformed into a palindrome, by removing at the most N characters from it.

    What do you mean "characters to remove"? I am given a string and a number N, and I am trying to find out if that string is K-drome or not.

    In what way does it not "work as expected"? It has some logic issue here, so not working as expected. do you have any suggestions for this?
