Wishing everyone writing INOI tomorrow best of luck !

Why do these exams not take place in Windows but in Ubuntu ?

I got 62,for some reason my first question’s some cases in 2nd subtask didn’t work. Otherwise would’ve easily scored 132

Can someone tell me what the recurrence relation was for the tiles question SUBTASK 3 where K=3? I just couldn’t get it to work.

How much did you get?

Getting 200

Someone create the excel sheet please.

Solution for p2 k=3

DP[i] =dp[i-1]+2*dp2[i-2]+dp[i-3]

Dp2[i]=dp3[i-1]+dp2[i-3]

dp3[i]=dp3[i-3]+dp[i-3]

answer is dp[n]

dp2[i] is the number of ways of to tile a 3*i grid with one corner removed and dp3[i] is the number of ways to tile a 3*i grid with the rightmost cell removed from first and second row
