License Plate Validator

You are given a string representing a license plate number. A license plate is considered valid if and only if it meets the following criteria:

• It contains exactly 6 characters.
• The first three characters are uppercase letters from A to Z.
• The last three characters are digits from 0 to 9.

In mathematical terms, if we let \(s\) be the plate string then the validity conditions can be stated as:

\[ |s| = 6, \quad s = L_1 L_2 L_3 D_1 D_2 D_3, \]

where each \(L_i\) is an uppercase letter (\(A \leq L_i \leq Z\)) and each \(D_j\) is a digit (\(0 \leq D_j \leq 9\)).

Your task is to implement a validator for license plate numbers that outputs True if the provided input string is valid according to the above criteria, and False otherwise.

inputFormat

The input consists of a single line containing a string which is the license plate number to be validated. This input is read from standard input.

outputFormat

Output a single line. Print True if the license plate is valid; otherwise, print False. The output should be written to standard output.
