  dot  product The  dot  tool returns the dot product of two arrays. import numpy A = numpy.array([ 1, 2 ]) B = numpy.array([ 3, 4 ]) print numpy.dot(A, B) #Output : 11 cross The  cross  tool returns the cross product of two arrays. import numpy A = numpy.array([ 1, 2 ]) B = numpy.array([ 3, 4 ]) print numpy.cross(A, B) #Output : -2 Task You are given two arrays   and  . Both have dimensions of  X . Your task is to compute their  matrix product . Input Format The first line contains the integer  . The next   lines contains   space separated integers of array  . The following   lines contains   space separated integers of array  . Output Format Print the matrix multiplication of   and  . Sample Input 2 1 2 3 4 1 2 3 4 Sample Output [[ 7 10] [15 22]] Solution import numpy n = int(input()) a = numpy.array([input().split() for _ in range(n)], int) b ...
