Hint

Sample 1 Explanation

There are 3 characters in the title, and all 3 characters are digit characters.

Sample 2 Explanation

There are $5$ characters in the title, including $1$ uppercase English letter, $1$ lowercase English letter, and $2$ digit characters, plus $1$ space. Since spaces are not counted in the result, the number of valid characters in the title is $4$.

Constraints

Let $|s|$ denote the length of the string $s$ (that is, the total number of characters and spaces in the string).
For $40\%$ of the testdata, $1 \le |s| \le 5$, and the input is guaranteed to be digit characters and the end-of-line newline character.
For $80\%$ of the testdata, $1 \le |s| \le 5$, and the input may only contain uppercase and lowercase English letters, digit characters, and the end-of-line newline character.
For $100\%$ of the testdata, $1 \le |s| \le 5$, and the input may contain uppercase and lowercase English letters, digit characters, spaces, and the end-of-line newline character.
