Hey, interesting contest. Please share the approach for the Assignment Time and The Droid Problem

It would be great if you could also share the approach for Crush 1 and Happy New Year

For crush, you had to check whether the digit sum is a prime or not. And since N is smaller than 10^9, you just had to compute less than 100 primes.


Oh thanks a lot for your help.

Assignment time : The three numbers which you entered were supposed to form the sides of a triangle. If the numbers entered could form a triangle, then cosine of the largest angle was the answer.

Really NaNDroid AnkurDroid : You had to output the number containing max number of set-bits


Happy New Year : Print the absolute difference between the number of even terms and odd terms of the array.


The editorials for all the problems are out. You may check them on the contest site.
