2. Algorithm modification (12 points) Replace the complex array equality condition in the if statement (step 4) of the NAIVE-STRING- MATCHER with a while loop so that it behaves thus: "compare P[1] with T[s+1), P[2] with T[s+2),..., compare P[m] with T[s+m) and if any of these comparisons returns FALSE then quit the character comparisons immediately otherwise continue until all m characters of P have been compared". Parts of the modified algorithm is given below. Fill in the blanks: NAVE-STRING-MATCHER-MODIFIED(T: array [1..n) of char; P: array [1..m) of char, , msn) 1 n = T.length 2. m = P.length 3. for s = 0 to nm j=1 while j m and P[_]==TE 6. j = 7. ifj == then print "Pattern occurs with shift" S When this algorithm's execution reaches step 7 within any execution of the outer for loop, the value of the variable j carries some useful information. What is it? (circle one) A. j = The number of character comparisons "P[])==T[S+j]" that succeeded during the execution of the while loop B.j = The number of character comparisons "P[])==T[s+j]" that failed during the execution of the while loop C. j = The number of characters of P that matched the substring T[S+1..s+m] D.j = The number of characters of P that matched the substring T[s+1..S+m] + 1 E. j = The number of characters of P that matched the substring T[s+1..s+m] - 1 2.
