Python 继续获取Kattis问题的运行时错误

Python 继续获取Kattis问题的运行时错误,python,python-3.x,python-2.7,Python,Python 3.x,Python 2.7,我正在努力解决这个问题() 当我提交我的最终代码时,我不断得到一个运行时错误。我不确定我的代码出了什么问题 # @Author Gansaikhan Shur # Another Brick in the Wall import sys # if len(sys.argv) < 2: # sys.exit("{}: needs an input file!".format(sys.argv[0])) # exit() sys_input = sys.argv[1] w

我正在努力解决这个问题()

#    sys.exit("{}: needs an input file!".format(sys.argv[0]))
#    exit()

sys_input = sys.argv[1]

with open(sys_input, "r") as f:
    data = [line.rstrip('\n') for line in f]
    hw_num = data[0].split()

#@作者甘赛汗·舒尔

导入系统
#如果len(系统argv)<2:

#退出()
sys_input=sys.argv[1]
打开(系统输入,“r”)作为f:
数据=[line.rstrip('\n'),用于f中的行]
hw_num=数据[0]。拆分()
len_bricks=数据[1]。拆分()
#分配给变量
高度=整数(hw_num[0])
宽度=整数(hw_num[1])
num_bricks=hw_num[2]
currHeight=0
对于范围内的i(高度):
电流高度=i+1
砖块宽度=0
对于j in len_砖:
砖块宽度+=int(j)
如果currHeight==高度,brick_width==宽度:
打印(“是”)
退出()
如果砖块宽度==宽度:
砖块宽度=0
持续
elif砖宽度>宽度:
打印(“否”)
退出()
其他:
持续
电流高度+=1

请让我知道我能做些什么让kattis.com接受此代码。谢谢运行时错误可能意味着:

  • 您得到的错误仅在运行时发生
  • 您得到了错误的结果(请参见下面的代码块-您的数据收集错误)
  • 您的代码运行太长

问题1:

您的代码不会增加高度:

如果你有像
bricks=[1]*10000000这样的数据,你的代码将运行looong,因为你永远不会增加你所处的高度。您需要处理整个列表,直到得到“否”

问题2:

您为此任务读入数据的方法是错误的-它不是基于文件的。请参阅-您需要从
sys.stdin
(下面的代码)中读取


您可以简化它:

def can_he_do_it(h,w,bricks):
    height = 0
    cur_w = 0

    # remove this line for kattis.com
    print("Project: Height: {} Width: {} with {}".format(h,w,bricks)) 

    # process all bricks - not the height or anythin else with range
    # bricks is all you got, place them down one by one, check lenght/height
    # and return False if you are too wide or not high enough
    # return True if you are high enough
    for brick in bricks:
        cur_w += brick        # add to current width and check

        if cur_w > w:         # too wide
            return False
        elif cur_w == w:      # exaclty correct, next row
            height += 1
            cur_w = 0

        if height == h:       # reach target heigth
            return True

    return False              # too few materials


def result(b):
     print("YES" if b else "NO") 

# replace with your number-read-code
result( can_he_do_it(2, 10, [5,5,5,5,5,5,]) )
result( can_he_do_it(2, 10, [5,5,5,3,5,5,]) )
result( can_he_do_it(2, 10, [5,5,5,]) ) 
输出:

Project: Height: 2 Width: 10 with [5, 5, 5, 5, 5, 5]
YES

Project: Height: 2 Width: 10 with [5, 5, 5, 3, 5, 5]
NO

Project: Height: 2 Width: 10 with [5, 5, 5]
NO

谢谢您的评论!你的解决方案看起来比我的好。但我在提交给Kattis.com时仍然有错误。我正在使用sys.argv[1]读取文件。但是网站一直告诉我有一个运行时错误。错误是什么?@JenniferGoncalves当我将它提交到Kattis.com时,状态栏下会显示“运行时错误”

YES
