[Solved]Karp Rabin Computation Unoptimized Failure Function Optimized Failure Function String Abra Q37083083

This is Karp-Rabin computation of an unoptimized failure functionand an optimized failure function for the string:ABRACADABRA.

Can someone explain step by step how the calculations are done?
