We consider an integer with at least 3 digits triple-balanced if, when split into three parts, the digits in every part sum up to the same number. We split numbers as follows:
abcdefghi - Standard case: the number of digits is divisable through 3: abc def ghi abcdefgh - Number % 3 == 2: The outer groups are both assigned another digit abc de fgh (the inner group will have one digit less than both outer groups) abcdefghij - Number % 3 == 1: The inner group is assigned the extra digit abc defg hij (the inner group will have one digit more than the outer groups)
Your task is to write a program, that, given an integer with at least 3 digits, determines whether the given number is triple-balanced and outputs a truthy or falsy value based on it's result.
333 -> True 343 -> False 3123 -> True 34725 -> True 456456 -> False 123222321 -> True
This is code-golf, so standard loopholes apply and may the shortest answer in bytes win!
