这到底是啥...
by xC41 @ 2020-02-05 13:00:40
```python
l=int(input())
```
@[_PyPy_](/user/316258)
这玩意

@[_PyPy_](/user/316258) input读一行，你读了两次

@[血色黄昏](/user/220426) 所以具体要怎么改，加个
```python
.split()
```
是吗

全RE，怎么改
```python
a=[[0]*1005 for i in range(1005)]
count=0
l,m=int(input("").split())
for i in range(0,l):
a[i]=0
for i in range(0,m):
x=int(input(""))
y=int(input(""))
for j in range(x,y):
if a[j]==0:
a[j]+=1
else:
continue
for i in range(0,l):
if a[i]==0:
count+=1
print(count)
```
(是不是没救了)

l, m = map(int, input().split())
