You're given an array of numbers, and you want to find 3 numbers that sum to 0 and output those 3 numbers. You can use each number multiple times. So if you're given the array [-1, 1, 2], you would output [-1, -1, 2] because -1 -1 +2=0

for encoding that {a,b,c,...,z}<->{1,2,3,...,26} if given a list of digit e.g. [1,2,3], this may represent {1,2,3}->{a,b,c} or {12,3}->{l,c} or {1,23}->{a,w}. so there are 3 possible interpretations for list [1,2,3] so, given a list of digit, calculate the number of possible interpretations for the list.
