Matrix addition

Problem to add the given two matrix.

Example-1:

Input    : n1 = [[1,2],[3,4]]  n2 = [[5,6],[7,8]]
Output   : [[6, 8], [10, 12]]

Example-2:

Input    : n1 = [[1,2,3],[4,5,6],[7,8,9]]  n2 = [[9,8,7],[6,5,4],[3,2,1]]
Output   : [[10, 10, 10], [10, 10, 10], [10, 10, 10]]

Solution

n1 = [[1,2],[3,4]]

n2 = [[5,6],[7,8]]

c = []

for i in range(len(n1)):

    k = []

    for j in range(len(n2)):

        k.append(0)

    c.append(k)

for x in range(len(n1)):

    for y in range(len(n2)):

        c[x][y] = n1[x][y]+n2[x][y]
        
print(c)

Output

[[6, 8], [10, 12]]
