148 for 11,12
and 100 for 10 and below i guess

24

Exactly I did the same one but I made a error in finding dp(i)(j) and I didn’t have time to debug so I couldn’t get get partial in this so my ioitc hopes are down ,I am in 10th standard

25

I think it would be 112 for 10th and below else too many people would qualify.

116 overall. I dont think they should make separate cutoffs.

There were two main insights:

  • The intersection constraint will implicitly be handled, since the base points have to be at least K + 1 apart.
  • You can represent a possible solution as the difference of two solutions which have the left region as the 0th column. (as you said, the prefix sum intuition)
