Valid Code Checker

You are given a string representing a numerical code. The code is considered valid if it meets the following criteria:

• It contains exactly two occurrences of the digit \(6\).
• There is at least one digit between the two \(6\)'s (i.e. the two \(6\)'s are non-adjacent).
• It does not contain the digit \(7\) anywhere.

Your task is to read a single line input from standard input which consists of the code, and output True if the code is valid according to the conditions above, and False otherwise.

inputFormat

Input: A single line containing a non-empty string of digits representing the code.
