Hi there
I have been trying to solve this Kata for a few hoursm, my submitted code has less than 10 lines length.
I have profiled my code, and it shows that the test case takes only 0.001 seconds on my computer.
However, the system still throws out a 'timeout' error.
I do not think my code is inefficient. Could anyone please help me?
regards
