我尝试使用Python3写程序，递交后它说：

“Runtime Error 0您的程序返回了1。”

但是我的程序明明可以正常运行 把自测数据丢进去的返回值都没问题 下面是我的代码内容：

cs = input()
cs1 = int(cs)
bb = 0
shuru = []
outlist = []
for i in range(0,2*cs1):
    iii = input()
    ii = iii.split(" ")
    shuru.append(ii)
for i in range(0,2*cs1):
    if (i+2)%2 == 0:
        n = int(shuru[i][0])
        k = int(shuru[i][1])
        w = int(shuru[i][2])
    else:
        for a in shuru[i]:
            if a == '':
                continue
            aa = int(a)
            if aa < w and k > 0:
                bb = bb + w
                k = k - 1
            else:
                bb = bb + aa
        outlist.append(bb)
        bb = 0
for i in outlist:
    print(i)

有什么解决方法吗？👀️
