Hi, I am quite new to codechef and also submitted my first problem. I am extremely sorry if this is not the right question to post. I am having an issue regarding submission. The issue is when I submit the solution against the custom input which is derived from problem description, it works!! (The program able to produce the right result). But then when I submit the solution not against the custom input, I get ‘NZEC’. Below is my attached code. If there is a problem with the code, please help me out. I couldn’t move one step further. The solution is for the problem *https://www.codechef.com/problems/HMAPPY2*

```
def gcd(a,b):
if a == b: return a
if a > b: return gcd(a-b,a)
return gcd(a,b-a)
def lcm(a,b):
return a*b // gcd(a,b)
testcases = int(input())
for t in range(testcases):
N,a,b,k = map(int,input().split())
x = N//a
y = N//b
z = N//lcm(a,b)
print('Win' if x+y-2*z >= k else 'Lose')
```
