def solve_problem(m, n, cards): flag = False num = 0 nums = set() for i in range(n): num = (num + cards[i]) % m # num += cards[i] #if num % m in nums: if num in nums: flag = True break nums.add(num) if flag: return 1 else: return 0 result = [] while True: try: input_value = input() if not input_value: for j in result: print(j) break else: n, m = map(int, input().split()) cards = list(map(int, input().split())) res = solve_problem(m, n, cards) result.append(res) except: break 以上代码哪里有问题，为啥没输出

以上代码中的问题在于输入的部分逻辑有误。在每次循环中，应该读取一行输入并解析为n和m的值，然后再读取一行输入并解析为cards列表。修改后的代码如下：

def solve_problem(m, n, cards):
    flag = False
    num = 0
    nums = set()
    for i in range(n):
        num = (num + cards[i]) % m
        if num in nums:
            flag = True
            break
        nums.add(num)
    if flag:
        return 1
    else:
        return 0

result = []
while True:
    try:
        input_value = input()
        if not input_value:
            for j in result:
                print(j)
            break
        else:
            n, m = map(int, input_value.split())
            cards = list(map(int, input().split()))
            res = solve_problem(m, n, cards)
            result.append(res)
    except:
        break

这样修改后的代码应该能正确输出结果。请确保在运行代码之前已经输入了相关的测试数据。
