Description
The disorder of a permutation.
Consider a permutation $\pi = [\pi_1,\ldots,\pi_n]$ and cyclically scanning $\pi$ from left to right and remove the elements $1$ through $n$ on this order one after the other. The disorder of $\pi$ is defined to be the number of times a position was not removed in this process.
For example, the disorder of $[3,5,2,1,4]$ is $8$ since on the first scan, 3,5,2 and 4 are not removed, on the second, 3,5 and 4, and on the third and last scan, 5 is once again not removed.

Code

    i = 1
    pos = 0
    count = 0
    while i < len(pi):
        if pi[pos] == i:
            i += 1
        elif pi[pos] > i:
            count += 1
        pos = (pos+1)%len(pi)
    return count
