Algorithm performance Give the order of magnitude Theta () for the following algorithm. Explain why your answer is correct. GET VALUES for A_1, A_2, .. ., A_n, and B_1, B_2, .. ., B_n Get value of n i = 1/* set i equal to 1 */DO WHILE (i lessthanorequalto n)/* for each of the n values in A */j = 1/* set j equal to 1 */DO WHILE (j lessthanorequalto n)/* Do n times *1 IF Ai = Bj THEN PRINT "Found it!" j = j + 1/* increment j */END DO WHILE i = i + 1/* increment i */END DO WHILE Explain what the algorithm does
