Mate,

Improve formatting or provide solution link.

Please format your code properly. Select whole code and press Ctrl + K to format it.

How are you removing details of players who are paired?

Thatās where ur solution is failing i guess. (May be at other points too, canāt tell because of bad formatting)

PS:Improve formatting, only then others would be able to help

You didnāt check if rating of j is compatible with i. i.e.

``````mini[i]<=rating[j]&&rating[j]<=maxi[i]
``````

Also the first if condition is not necessary, you donāt need to check constraints of input.

1)Timings must be exactly equal, change that line to if(time[i]==time[j])

2)(israted[i]==āratedā||israted[i]==āunratedā)&&(israted[j]==āratedā||israted[j]==āunratedā)) is always true, you should check whether both are either āratedā or āunratedā

Why are you checking the constraints? The inputs will always satisfy the constraints. Remove unnecessary lines.

Read the question 100 times and then start writing code for it !!!

i have solved this que but it shows wrong answer and i am not able to find any error in my solutionā¦ i had also solved the que POLY of NOV challenge for 2nd subtaskā¦ why this happens to meā¦
please give me some tricks or a way to know where i am wrongā¦

Of what relevance is this line here?

@vijju123 I think heās trying to say that he solved a very hard āpolyā problem(Show off) but why he couldnāt solve this problem!!

You can try looking at this solution. It is almost as same as yours.

He solved it only for 30 points, which was easily available on internet. Whats there to show off lol

***Hey, YOU can go through my codes.It is very simple.

Read the question 100 times and the competition over!!

It was on the internet? Dang I missed the chance (ą²„ŁŁŁŁŁŁŁŁŁŁą²„)

@vijju123 , Can u tell me what have u edited in this code ??
I have submitted this code & it worked fine.

I fixed the formatting. It was appearing very clumsy if you recall, no new lines and stuff.

ohhh, thanx
