Question: Consider the pattern P = a b a c a b and the string S=bacaabaccabacabaabb Assume the following numerical codes for the letters a,

Consider the pattern P = a b a c a b and the string S=bacaabaccabacabaabb Assume the following numerical codes for the letters a, b, and c, code(a)=1, code(b)=2, and code(c)=3, so the pattern P = a b a c a b is represented by the number 121312. Use Rabin-Karp algorithm to verify if P appears in S. Use modular hashing with R = 10 and hash(s) = s mod 997 (as in the textbook and lecture notes). How many character comparisons are required by the Rabin-Karp algorithm?
