Check this slight update to your code.

47347385

Your code should have the if-condition (i > 0 and p[i] == q[i-1]) to avoid accessing q[-1] when i = 0. The updated code did not pass test case 19 as it computed the n-letter string to be "babab" whereas the correct string should be "ababa", as both prefix and suffix of length 1 are "a".

You may check the the following solution as well as the tutorial for hints on how the correct string is computed.
