Description
The number of upper interactions of a Dyck path.
An upper interaction in a Dyck path is defined as the occurrence of a factor $A^{k}$$B^{k}$ for any ${k ≥ 1}$, where ${A}$ is a down-step and ${B}$ is a up-step.
Code
def statistic(List):
    interactions = 0
    i = 0
    count = 0
    while i < len(List):
        if List[i] == 0:
            if List[i-1] == 1:
                count = 0
            count = count + 1
        if List[i] == 1 and count > 0:
            interactions = interactions + 1
            count = count - 1
        i  = i + 1
    return interactions
