### Detect Capitol

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:
1. All letters in this word are capitals, like "USA".
2. All letters in this word are not capitals, like "leetcode".
3. Only the first letter in this word is capital if it has more than one letter, 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.

### Solution

• We need to have a counter variable
• if the difference between the current character and capitol character is greater than zero than increment the count
• If the count is zero or the count and length are same or count is 1 and difference is greater than zero return true
```package Algorithms.Strings;

public class DetectCapitol {
public static boolean get(String word)
{
int cnt=0;
for(char c:word.toCharArray())
//If the condition is true we are counter is incremented
if('Z' -c >= 0) cnt++;
//If the count is zero or the count and length are ```
```                    //same and count is 1 and difference is greater than zero
return ((cnt==0 ||cnt==word.length())|| ```
```                           (cnt==1 && 'Z' - word.charAt(0) >=0));

}

}
```
