stuck in count inversion problem
I think I am suppose count number of times series does not follow rule.
So I tried something like:
def count_inversion(sequence): sequence = list(sequence) count = 0 for i in sequence: if sequence[sequence.index(i)] - sequence[(sequence.index(i)-1)] != 1: count = (count + 1) return count
But it is not giving me correct answer and I can't figure it out what is wrong!
