[leetcode-in-go] 0058-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.

Example:

Input: “Hello World”
Output: 5

func lengthOfLastWord(s string) int {
	cnt := 0
L:
	for i := len(s) - 1; i >= 0; i-- {
		if s[i] == ' ' {
			continue
		} else {
			for ; i >= 0; i-- {
				if s[i] != ' ' {
					cnt++
				} else {
					break L
				}
			}
		}
	}
	return cnt
}
