in the statement:"The other multipliers has a form of X^N or X, where X is a variable (small Latin letter), N – nonnegative integer that doesn’t exceed 100 (might be with the leading zeros)."

in my class N -unsigned char (0..255)
therefore my answer a^143*b^99

it's problem in statement.

now i must rewrite my hash function!
