You are right, I was mixing them up. I was apparently being dyslexic when I read my output lines.

Thanks!

Maybe there is another corner case with the null or empty?

I have taken care of boundary cases like a or b being null.
And then if a length is zero or b length is zero, I will return false.
Could you tell me if where I am going wrong?

Did you think of corner cases?

Trying in Java.
I'm having issue with Test case # 4. Other test cases passed.
Pls help.

I think you are mixing test 5 and test 6. In doubt post your test but there are no errors in the tests.

In C#, I'm having trouble with test case #5. After reading through comments, a couple of others have too.

Input:
a=[121, 144, 19, 161, 19, 144, 19, 11, 1008]
b=[121, 14641, 20736, 36100, 25921, 361, 20736, 361]

This is basically the invalid example from the description with "1008" being added to array "a", but this time it's expected to return true. I cannot wrap my head around why it is expected to return true, when it is shown that it should return false in the description of the kata itself. Any suggestions?
