Python中的NZEC错误

问题描述

这是一段简单的代码，假设读取 n 个数字并假设打印这 n 个数字中有多少个数字可以被 k 整除

this is a simple piece of code which is suppose to read n numbers and suppose to print how many numbers out of these n numbers are divisible by k

n=int(raw_input())
k=int(raw_input())
ans=0
while n > 0:
  t=int(raw_input())
  if(t%k == 0):
    ans = ans + 1
  n = n - 1
print ans 

我在 codechef 上遇到了 NZEC 错误.有人可以指出问题出在哪里吗?自上周以来，这个 NZEC 错误一直困扰着我.我是 python 的新手，在互联网上搜索了很多，但找不到任何具体的东西.我得到的答案是，当堆栈大小超出限制时会发生 NZEC 错误.但是我的这段代码有什么问题?

I got a NZEC error for this on codechef. Can someone point out where does the issue lie? This NZEC error has bothered me a lot since last week. I am new to python and have searched a lot on internet but could not find anything concrete. I got the answer that NZEC error occurs when the stack size goes beyond limit. But what is the issue with my this code?

推荐答案

我想 codechef 的问题是这个.您应该考虑到 n 和 k 的值大约为 10^7，这可能是您的程序有问题.

I suppose the codechef question is this one. You should take in account that the value of n and k are around 10^7, which could be a problem with your program.

此外，n 和 k 在同一行上.您使用了 raw_input 两次，因此您正在阅读两行.这可以通过使用来解决:

Also, n and k are on the same line. You are using raw_input twice, so you are reading two lines. This can be solved by using:

n, k = raw_input().split(" ")
n = int(n)
k = int(k)

如果这没有帮助，您可以尝试遍历 xrange，或者使用不同的算法.

If that won't help, you could try looping over an xrange instead, or using a different algorithm.
