[Solved] A company has launched a new text editor that allows users to enter English letters

A company has launched a new text editor that allows users to enter English letters, numbers and whitespaces only. If a user attempts to enter any other type of character, it is counted as a miss. Given a string of text, write an algorithm to help the developer detect the number of misses by a given user in the given input.

Input

The input consists of a string textinput, representing the text that is entered in the text editor by the user.

Output

Print an integer representing the number of misses by a given user in the given input.

Example

Input:

aa a234bc@ sads hsagd^

Output:

3

Explanation:

The characters that are counted as misses by the editor are l’@’s.]

Solution

def editorMisses(textinput):
    count = 0
    for i in textinput:
        if i.isalpha() == False and i.isdigit() == False and i.isspace() == False:
            count += 1
    return count

    public static int editorMisses(String input) {
        int miss = 0;
        for (int i = 0; i < input.length(); i++) {
            if (!Character.isLetterOrDigit(input.charAt(i)) && !Character.isWhitespace(input.charAt(i))) {
                miss++;
            }
        }
        return miss;
    }
