[LeetCode] 58. Length of Last Word

lol，工作很繁重，脑子不是很清楚，只能拿一道简单到逆天的题目充数了 ╮(￣▽￣)╭　

	class Solution {
	public int lengthOfLastWord(String s) {
	int end = s.length() - 1;
	while (end >= 0 && s.charAt(end) == ' ') {
	end--;
	}
	int start = end;
	while (start >= 0 && s.charAt(start) != ' ') {
	start--;
	}
	if (end >= 0) {
	return end - start;
	}
	return 0;
	}
	}
