# What is wrong with my solution to Real Obtuse ?

I have tried every possible test case which came to my mind yet I am not able to find even a signle case where my solution is returning wrong answer. Please help ?

Here is the question link : Real Obtuse.

Note that there was a confusion that my programme would not be able to detect the odd K and therefore will give output 0. But please note that the division of k is a float. So the temp will store 2.5 if K is 5, therefore either if or else-if block will be executed.

Your answer would be wrong for odd k while determining diametric opposite point… because of integer division you are taking… Ex…

1

3 3 1

another test case would be 10 9 2, here answer should be 2 not 4…

Hey @kauts_kanu thanks for yor ans, but the output to the above input coming 1 which is right ! Its happening cause I have a float division and so the value of temp will be 2.5 and not 2. So therefore the “else-if block” will be executed because 2 < 2.5 !
I hope u got what I meant !

Ok… I just saw it… I saw your code on phone that time so could not cross check test case… Let me see what is wrong then…

It is due to precision issues. You see the input here is 106+1, but `k` gets the value of 106 only.

Ok man. Thank you @kauts_kanu !

Although I will also have to add a new condition for checking weather K is odd or not.
@meooow So changing the float to long will do the trick ?

Your code is giving 2 as output for 3 3 1 but answer should be 0… Hope this will help…

Yep, that should work.

@kauts_kanu, actually by-mistake, I linked to the previous file, the link is updated. And it’s giving 0 and 2 for the above-mentioned input!
And again thank you for the help!
