Output: 29
expected: 34
Failed.
Because of this line j = j == 0? 25 : j - 1; The counter[j] can't be circled back because duplicate task is not allowed within this n + 1 time interval.

I think the time complexity is O(n) as the array is of size 26 regardless of size of input and so the sort function takes O(26log26) = O(1). Therefore the incrementing of the array for each letter initially is the bound of the algorithm at O(n)

Can you tell clearly why time is time+(n-i+1)
