in the name of allah, most mercifull

i try to solve this problem

but it gives me wrong answer on test 1

here is my code

logic is correct and i think it doesn't work because it is interactive

i hope somebody guide me.

in the name of allah, most merciful

i'm amin najafvand.

i'm so sorry about writing somethings that wastes some (participents of codeforces)'s times

it was inhumane work

i promise that from this time i don't write some silly things.

i hope that participents forgive me.

have good time.

In the Name of Allah, the Compassionate, the Merciful.

codeforces can add a part for number of successful attempt for hacking.

i hope that we be able to see it in feature.

also i hope that who gives me negative mark tells me my wrong to correct it.
