python最后一个测试点提示答案错误，各位老哥帮忙看下

N,M = map(int,input().split(" "))

for i in range(N):
    sum =0
    num = 0

    ipt_list = list(map(int,input().split(" ")))
    sort_list = sorted(ipt_list[1:])

    for k in sort_list:
        if 0<=k<=M:
            pass
        else:
            sort_list.remove(k)
    for j in sort_list[1:-1]:
        sum = sum + j
        num += 1
    sum = (sum/num + ipt_list[0])/2
    sum = float(sum)
    a,b = str(sum).split(".")
    if int(b[0])>=5:
        a = int(a)+1
    print(a)
