Kattis 1dfroggerhard题目超时求助：多进程尝试出错求优化

我在解决Kattis平台的1dfroggerhard题目时，代码运行超时。作为编程新手，我第一次尝试用multiprocessing做优化，但运行结果错误。我的代码如下：

from multiprocessing import Process

def task(check_tiles, tiles, position, j):
    check_tiles.clear()
    for k in range(len(tiles)):
        check_tiles.append(0)
    magic = tiles[j]
    global wins
    while(True):
        if(tiles[position] == magic):
            wins += 1
            break
        elif((position + tiles[position]) < 0):
            break
        elif((position + tiles[position]) > no_of_tiles - 1):
            break
        else:
            check_tiles[position] = 1
            position += tiles[position]
            if(check_tiles[position] == 1):
                break

no_of_tiles = input()
no_of_tiles = int(no_of_tiles)

wins = 0
tiles = []
check_tiles = []
str2 = input()
tiles = str2.split(' ')
tiles = [int(i) for i in tiles]

for i in range(no_of_tiles):
    position = i
    processes = [Process(target=task(check_tiles, tiles, position, j), args=(j,)) for j in range(no_of_tiles)]
    for process in processes:
        process.start()
print(wins)

我尝试对第一个for循环进行多进程处理，但得到的答案错误，希望获得缩短运行时间的建议。
