Problem Statement

Given are two NN-dimensional vectors A=(A1,A2,A3,,AN)A = (A_1, A_2, A_3, \dots, A_N) and B=(B1,B2,B3,,BN)B = (B_1, B_2, B_3, \dots, B_N). Determine whether the inner product of AA and BB is 00. In other words, determine whether A1B1+A2B2+A3B3++ANBN=0A_1B_1 + A_2B_2 + A_3B_3 + \dots + A_NB_N = 0.
