Matrix Negative

Problem

Return the additive inverse of matrix A: every entry is negated.

B[i][j] = -A[i][j], so A + B is the zero matrix.

Hint

Negate each entry; the shape stays the same.

case 1

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

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

case 2

in: [[[0,0]]]

expected: [[0,0]]

case 3

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

expected: [[-1.5,2.5]]

case 4

in: [[[0]]]

expected: [[0]]
