Step-by-step explanation:
in matrix, arrays are placed in rows , which represents the horizontal sides from left to right, while arrays in the column are placed vertically from top to bottom. Here, we placed the arrays in a 4x4 matrix
for a a) {(1, 2), (1, 3), (1, 4), (2, 3), (2, 4), (3, 4)}
for b
b) {(1, 1), (1, 4), (2, 2), (3, 3), (4, 1)}
for c) {(1, 2), (1, 3), (1, 4), (2, 1), (2, 3), (2, 4), (3, 1), (3, 2), (3, 4), (4, 1), (4, 2), (4, 3)}
for d d) {(2, 4), (3, 1), (3, 2), (3, 4)}
