旋转矩阵环的第一行出现错误

Question

在这段代码中，我收到了以下错误

Enter M: 
Traceback (most recent call last):
File "main.py", line 1, in <module>
M = int(input("Enter M: "))
ValueError: invalid literal for int() with base 10: '4 4'

问题在下方

给定一个M*N阶矩阵和一个值K，编写一个程序将矩阵的每个环顺时针旋转K个元素。如果在任何一个环中有小于或等于K个元素，则不要旋转该环。

输入

第一行输入将是两个空格分隔的整数，表示M和N。接下来的M行将包含N个空格分隔的整数。下一行将包含一个整数，表示K.

输出

通过将矩阵旋转K个元素，输出应该是M*N矩阵。

解释

例如，如果给定的M和N分别为4和4。如果矩阵元素1 2 3 45 6 7 89 10 11 1213 14 15 16如果给定的K是3。将矩阵的每个环旋转3个元素。在上述矩阵中，元素(1、2、3、4、8、12、16、15、14、13、9、5(是环，类似地，元素(6、7、11、10(将构成环。因此，通过将每个环沿顺时针方向旋转3个元件，将得到(13，9，5，1，2，3，4，8，12，16，15，14(和(10，6，7，11(。所以输出应该是13 9 5 114 7 11 215 6 10 316 12 8 4

代码低于

M = int(input("Enter M: "))
N = int(input("Enter N: "))

A = [[0]*N for x in range(M)]
for i in range(0, M):
for j in range(0, N):

K = int(input("Enter K: "))
Ring = (min(M, N) + 1) // 2

count = 0
r = 0
d = 0
l = 0
u = 0

for i in range(Ring):
size = 2*(M-2*i) + 2*(N-2*i) - 4
if M-2*i == 1:

print("")

print("")

而且没有得到预期的测试用例输出，测试用例是

输入数据的代码(问题的输入部分(：

M, N = [int(x) for x in input("Enter M N: ").split(' ')]
nums = []
for i in range(0, M):
nums.append([int(x) for x in input(f"Enter {i} row with {N} space-separated integers: ").split(' ')])
K = input("Enter integer K: ")
print(f"You entered:nM={M},N={N}")
print(f"Lists of entered space-separated integers is:n{nums}")
print(f"K={K}")

输出

Enter M N: 3 3
Enter 0 row with 3 space-separated integers: 1 2 3
Enter 1 row with 3 space-separated integers: 4 5 6
Enter 2 row with 3 space-separated integers: 7 8 9
Enter integer K: 10
You entered:
M=3,N=3
Lists of entered space-separated integers is:
[[1, 2, 3], [4, 5, 6], [7, 8, 9]]
K=10
