Array spiral print anticlockwise

#1


testcase 4 is wrong,help to resolve.

#2

@Yukta Consider this test case:
2 6
1 2 3 4 5 6
7 8 9 10 11 12

Expected Output:
1, 7, 8, 9, 10, 11, 12, 6, 5, 4, 3, 2, END

Your Output:
1, 7, 8, 9, 10, 11, 12, 6, 2, 3, 4, 5, END

Hope this helps :slightly_smiling_face:
