Count Character Categories

You are given a string which contains a mix of uppercase letters, lowercase letters, and digits. Your task is to count the number of uppercase letters, lowercase letters, and digits, and then output a dictionary with these three counts. However, if the string contains any characters that are not an uppercase letter, a lowercase letter, or a digit, you should output False.

In other words, if we denote:

• $$U$$ as the set of uppercase letters,
• $$L$$ as the set of lowercase letters, and
• $$D$$ as the set of digits,

Then, for a given string \(s\), you need to compute:

[ |U| = \text{number of characters in } s \text{ that are uppercase}, ] [ |L| = \text{number of characters in } s \text{ that are lowercase}, ] [ |D| = \text{number of characters in } s \text{ that are digits}. ]

If any other character is found, output False.

Note: The output should be formatted exactly as a Python dictionary if the string is valid.

inputFormat

The input consists of a single line containing the string \(s\). This string may be empty.

outputFormat

If the string is valid (only contains uppercase letters, lowercase letters, or digits), output a dictionary printed as a string with keys 'uppercase', 'lowercase', and 'digits' mapping to their respective counts. Otherwise, output the word False.
