bhaiya,
it already over at 8pm…it’s just you don’t have registered id for ACM contest…
I might be last person on earth to cheat…I have not cheated once in my life whether its sports or studies…it’s record of mine i’m proud of…that day i quitted the contest…but my wrong code was bothering me so I asked you…I forgot that day that contest would have been still running !

#4

no issue bro, acutally the questions are not accessible to me so i thought these questions are part of any ongoing contest , hence i told u to ask later.

#5

@aman212yadav
yes bhaiya. I just wanted to make you aware of my nature of not cheating… I know that you don’t know me and almost everyone don’t resist malpractices !!

I’m sharing question copy-paste format:-

#6

use mod property in this line ->

         a[i]=a[i-1]+a[i-2]+a[i-3];

also u have used a[1]=0 (once cross check what they have defined for 0,1,2)

#7

@aman212yadav

a[1]=0 only.

What’s the mod property?
what’s wrong in my logic?

#8

modulo arithmetic property.

    a[i]=(a[i-1]+a[i-2]+a[i-3])%31;
