Given a word, you need to judge whether the usage of capitals in it is right or not.
We define the usage of capitals in a word to be right when one of the following cases holds:
Example 1:
Input: "USA" Output: True
Example 2:
Input: "FlaG" Output: False
Note: The input will be a non-empty word consisting of uppercase and lowercase latin letters.
public class Solution {public bool DetectCapitalUse(string word) {string upCopy = word.ToUpper();string lowCopy = word.ToLower();if (word == upCopy || word == lowCopy) {return true;}string first = word.Substring(0, 1);string last = word.Substring(1, word.Length - 1);if (first.ToUpper() == first && last.ToLower() == last) {return true;}return false;}}
