问题： 冒泡排序是一种算法，它对长度为N的序列进行排序，以便检查两个相邻元素以更改其位置。气泡排序可以进行N次，如下所示。
将第一个值与第二个值进行比较，如果第一个值较大，则更改位置。 将第二个值与第三个值进行比较，如果第二个值较大，它将更改其位置。 ... 比较N-1和N-值，如果N-1的值较大则更改位置。 “ Supchan”我当然知道气泡排序的结果。但是，由于N非常大，因此需要花费很长时间来执行上述步骤K次。编写一个程序，以帮助您找到气泡排序的中间过程。
我的代码
def bubble(list):
temp = 0
for i in range(0, len(list)):
for j in range(i+1, len(list)):
if (list[i] > list[j]):
temp = list[i]
list[i] = list[j]
list[j] = temp
return list
numbers = input()
items = [int(num) for num in numbers.split()]
print(bubble(items))
测试条件
N and K are given in the first line.
The second line gives the status of the first sequence. That is, N integers forming the first sequence are given in turn, with spaces between them.
1 ≤ N ≤ 100,000
1 ≤ K ≤ N
Each term in the sequence is an integer from 1 to 1,000,000,000.
输入和输出
input: 3 1 2 5 4
output: 1 2 3 4 5
我编写的代码似乎运行良好。但是，编码测试的等级拒绝了我。
我无法理解原因，因为原因未列出。我的代码有问题吗？
答案 0 :(得分：0)

numbers = input()
测试输入的格式可能是
numbers = raw_input()
代替
1 5 6 4 3
使用'1 5 6 4 3'
运行时可能会导致错误
