Length of Last Word

Length of Last Word

Given a string s consists of upper/lower-case alphabets and empty space characters ' ', return the length of last word in the string.

If the last word does not exist, return 0.

Note: A word is defined as a character sequence consists of non-space characters only.

For example, 
Given s = "Hello World",
return 5.

        bool recount = true;
        
        while (*s != '\0') {
            if (*s != ' ') {
                if (recount) {
                    count = 1;
                    recount = false;
