Hello guys..

I made this account just to say some stuff and asking for advices that maybe i don't have enough courage to talk about in public with my main account...

Now i am just asking for your opinion.

If someone you don't know asked you for some help in private chat do you consider this rude?

Even if he asked if you have enough time or not would this still be disturbing?

With help i mean like problems or road map or brief question etc..

Hello guys..

I was trying to solve this problem But sadly i am getting WA cause i can not answer the following question.

Which point do we consider a good point? for example (..) we can place a domino but i don't know which point of them to mark.

Cause obviously if i decided to make the left one then i will get WA for query which take only the first part something like #.. and same for the right part ..# and of course same for vertical.

I am hoping that someone can help me and here's my attempt even though it's wrong.

Thank you.

Hello guys..

sorry if this question seemed dummy but not typing return 0 would cause me WA?

i believe that i heard that judge would wait for return 0 some times? not typing it never caused me a problem and i know that someone would say then just type it... but i am wondering about the reason and if this is even correct..

Thank you..
