Maximum Number of Words You Can Type
There is a malfunctioning keyboard where some letter keys do not work. All other keys on the keyboard work properly.
Given a string text of words separated by a single space with no leading or trailing spaces, and a string brokenLetters of all distinct letter keys that are broken, return the number of words in text you can fully type using this keyboard.
Example 1
Input
text = "hello world", brokenLetters = "ad"Output
1We cannot type "world" because the 'd' key is broken.
Example 2
Input
text = "leet code", brokenLetters = "lt"Output
1We cannot type "leet" because the 'l' and 't' keys are broken.
Constraints
- 1 <= text.length <= 10^4
- 0 <= brokenLetters.length <= 26
- text consists of words separated by a single space without any leading or trailing spaces.
- Each word only consists of lowercase English letters.
- brokenLetters consists of distinct lowercase English letters.
