[코드]

# you can write to stdout for debugging purposes, e.g.
# print("this is a debug message")

def solution(A):
    # write your code in Python 3.6
    answer=1
    i=0
    while True:
        if A[i] == -1:
            break;
        else:
            i = A[i]
            answer+=1
    return answer
    
# PassTheMessage is recommended
