                ##### target checksum is 88692587, because sum starts with 1, and not 0, we can start sum with 0
##### and treat the checksum as 88692588.
##### because we are using only integers, the checksum must be divisable by the length of the word.
##### The only reasonable lengths for this are 9, 12, 18. 12 being the most reasonable.
##### The equation were solving is:
#####
##### 88692588 / (n + 1) = sum from 1 to N of: (i^3 * Ai^2)
##### where n + 1 is the length of the string, i is the index of the character, Ai is the index of the character in the "tab" array
##### range of characters in tab array: 0, 19-85
