Matrix Addition

Problem

Add two matrices A and B of the same shape elementwise.

Return C with C[i][j] = A[i][j] + B[i][j].

Hint

Loop over each row and column index.

case 1

in: [[[1,2],[3,4]],[[5,6],[7,8]]]

expected: [[6,8],[10,12]]

case 2

in: [[[0,0],[0,0]],[[1,-1],[-2,2]]]

expected: [[1,-1],[-2,2]]

case 3

in: [[[-1,-2],[-3,-4]],[[1,2],[3,4]]]

expected: [[0,0],[0,0]]

case 4

in: [[[1.5,2.5]],[[0.5,-1.5]]]

expected: [[2,1]]
