A. 为了盐城鸡蛋饼什么都干得出来 (Easy Version)

def solution():
    n, m = map(int, input().split())

    a = list(map(int, input().split()))
    x = max(a) - min(a)
    print(x)

I. 你说的对，但是做不了一点

def main():
    n, m = map(int, input().split())
    p = max(map(int, input().split()))
    s = 0
    for i in range(m):

    print(s)
    return

main()

J. 舰长，该凹深渊了

def main():

                a[name] = time
        else:

    if "TannicAcid" not in a.keys():
        print(n + 1)
        return
    r = 1
    for name, time in a.items():
