初步代码（纠错）：

n = int(input())
A = list(map(int, input().split()))
B = list(map(int, input().split()))
C = list(map(int, input().split()))

# 胜利状态的函数编写：
def vic(name):
    f = []
    cnt = 0
    s = 0
    if name == 'x':
        for i in range(n):
            w = A[i] - B[i] - C[i]
            f.append(w)

        f.sort()
        i = n
        while i:
            i -= 1
            s += f[i]
            if s <= 0:
                return cnt
            cnt += 1

    if name == 'y':
        for i in range(n):
            w = B[i] - A[i] - C[i]
            f.append(w)

        f.sort()
        i = n
        while i:
            i -= 1
            s += f[i]
            if s <= 0:
                return cnt
            cnt += 1

    if name == 'z':
        for i in range(n):
            w = C[i] - A[i] - B[i]
            f.append(w)

        f.sort()
        i = n
        while i:
            i -= 1
            s += f[i]
            if s <= 0:
                return cnt
            cnt += 1

X = vic('x')
Y = vic('y')
Z = vic('z')
if X == 0 and Y == 0 and Z == 0:
    print(-1)
else:
    print(max(X, Y, Z))

上面代码我只写了当Ai - Bi - Ci在下一个变化量达成 <= 0 的状态，忽略了当所有事件的贡献值之和始终为正（ > 0 ）时的情况，故而报错：unorderable types: NoneType > int，花了我半小时时间去debug，sb了

故而有了下面这串修正代码，更简洁直观

import sys
n = int(input())
A = list(map(int, input().split()))
B = list(map(int, input().split()))
C = list(map(int, input().split()))

all_equal = all(a == b == c for a, b, c in zip(A, B, C))
# 当所有Ai == Bi == Ci的情况
if all_equal:
    print(-1)
    sys.exit()

# 胜利状态的函数编写：
def vic(name):
    f = []
    if name == 'x':
        for i in range(n):
            f.append(A[i] - B[i] - C[i])
    elif name == 'y':
        for i in range(n):
            f.append(B[i] - A[i] - C[i])
    elif name == 'z':
        for i in range(n):
            f.append(C[i] - A[i] - B[i])

    # 降序排序，替代逆序遍历
    f.sort(reverse=True)

    s = 0
    cnt = 0
    for val in f:
        s += val
        if s <= 0:
            break
        cnt += 1
    return cnt  # 确保始终返回整数

X = vic('x')
Y = vic('y')
Z = vic('z')
max_events = max(X, Y, Z)
print(max_events if max_events > 0 else -1)  # 当cnt = 0时就是所有事件都无法达成三国中的任意一国胜出，所以直接输出-1就是了
