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:
- All letters in this word are capitals, like "USA".
- All letters in this word are not capitals, like "leetcode".
- Only the first letter in this word is capital, like "Google".
Otherwise, we define that this word doesn‘t use capitals in a right way.
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.
class Solution { public boolean detectCapitalUse(String word) { int numCap = 0; int i = 0; while (i word.length()) { if (Character.isUpperCase(word.charAt(i))) { numCap += 1; } i += 1; } if (Character.isUpperCase(word.charAt(0))) { return numCap == 1 || numCap == word.length(); } return numCap == 0; } }
