failed to pass the 5th test

My code passed the first 4 tests, but failed in 5th test. I don't know why the result is 4181. Please help! +++++++++++++++++++++++++++++++++++++++++

def count_inversion(sequence):
    """
        Count inversions in a sequence of numbers
    """
    count=0
    for n in range(len(sequence)-1):
        m=1
    #compare a number(n) and the next number(m), and then the next of the next number(m+1)...
        while sequence[n]>sequence[n+m]:
            count+=1
            m+=1
            if n+m==len(sequence):
                break
            else:
                continue        
    return count
