# [520. Detect Capital](https://leetcode.com/problems/detect-capital/)
2+
3+
4+
## 题目
5+
6+
We define the usage of capitals in a word to be right when one of the following cases holds:
7+
8+
All letters in this word are capitals, like "USA".
9+
10+
All letters in this word are not capitals, like "leetcode".
11+
12+
Only the first letter in this word is capital, like "Google".
13+
14+
Given a string word, return true if the usage of capitals in it is right.
15+
16+
**Example 1:**
17+
18+
```
19+
Input: word = "USA"
20+
Output: true
21+
```
22+
23+
**Example 2:**
24+
25+
```
26+
Input: word = "FlaG"
27+
Output: false
28+
```
29+
30+
**Constraints:**
31+
32+
- 1 <= word.length <= 100
33+
- word consists of lowercase and uppercase English letters.
34+
35+
## 题目大意
36+
37+
我们定义，在以下情况时，单词的大写用法是正确的：
38+
39+
全部字母都是大写，比如 "USA" 。
40+
单词中所有字母都不是大写，比如 "leetcode" 。
41+
如果单词不只含有一个字母，只有首字母大写，比如"Google" 。
42+
43+
给你一个字符串 word 。如果大写用法正确，返回 true ；否则，返回 false 。
44+
45+
## 解题思路
46+
47+
- 把 word 分别转换为全部小写 wLower，全部大写 wUpper，首字母大写的字符串 wCaptial
48+
- 判断 word 是否等于 wLower, wUpper, wCaptial 中的一个，如果是返回 true，否则返回 false
49+
50+
## 代码
51+
52+
```go
53+
54+
package leetcode
55+
56+
import "strings"
57+
58+
func detectCapitalUse(word string) bool {
59+
wLower := strings.ToLower(word)
60+
wUpper := strings.ToUpper(word)
61+
wCaptial := strings.ToUpper(string(word[0])) + strings.ToLower(string(word[1:]))
62+
if wCaptial == word || wLower == word || wUpper == word {
63+
return true
64+
}
65+
return false
66+
}
67+
