15 6 10 3

16 12 8 4

can anyone give the code correct?

Answer 1

M, N = input().split(' ')
M, N = int(M), int(N)
matrix = []
for _ in range(M):
	row = [int(x) for x in input().split(' ')]
	matrix.append(row)

K = int(input())

values = matrix[0][:-1] + [x[-1] for x in matrix][:-1] + matrix[-1][::-1][:-1] + [x[0] for x in matrix][::-1][:-1]

values = values[-K:] + values[:-K]

output = matrix

idxs = [(0, j) for j in range(N)][:-1] + [(i, N - 1) for i in range(M)][:-1] + [(M - 1, j) for j in range(N)][::-1][:-1] + [(i, 0) for i in range(M)][::-1][:-1]

idx = 0
for i, j in idxs:
	output[i][j] = values[idx]
	idx += 1

for i in output:
    for j in i:
        print(j, end=' ')
    print()
