Can someone please help me out to find out the problem in this question of may long challenge 2020.

I am unable to identify the missing edge case since many days

I could only find one mistake:

```
if(x==0 or y==0):
print(0)
```

if x or y is equal to 0, you are printing 0. but what if `L>0`

You need to print `L`

instead in this case because 0 is not always within the range of L and R
