# why my code is not working for the problem chef and notebooks its problem code is CNOTE

You are printing `UnLuckyChef` instead of `UnluckyChef`

The ‘L’ must be in lowercase!

There are couple of things :

1. The ‘L’ must be in lowercase! (i.e. print UnluckyChef instead of UnLuckyChef)

2. Your code prints the result after every input. Dont do that print all the results at the end. Pls check “Sample input” & “Sample Output” given. Check with the following input :

2

3 1 2 2

3 4

2 2

3 1 2 2

2 3

2 3

Expected Output :

LuckyChef

UnluckyChef

2

3 1 2 2

3 4

2 2

Luckychef

3 1 2 2

2 3

2 3

UnluckyChef

3. Then there is a logical error. Check with the following input :

1

3 1 2 4

2 5

2 5

2 5

2 5

Expected Output :

Unluckychef
