Write a function, dotProduct(), that takes in two matrices (as 2D array of integers), and returns a third matrix that is the Dot Product of the two. If you never studied the Dot Product, read here for an explanation and how to compute it: https://www.mathsisfun.com/algebra/matrix-multiplying.html If the two matrices do not have the right dimensions to compute the Dot Product, your function should return None. Remember, if the number of columns of the 1st matrix is not equal to the number of rows of the 2nd matrix, the Dot Product cannot be computed. You can safely assume that the two 2D arrays have inner arrays of equal length (i.e. not a jagged array). Examples # from the article above matrix1 = [[3, 4, 2]] matrix2 = [ [13, 9, 7, 15], [8, 7, 4, 6], [6, 4, 0, 3], ] dotProduct(matrix1, matrix2) returns [[83, 63, 37, 75]]
