I literally don't know how my solution for Maximal Sum worked.
Maximal Expression can anyone explain the case for n > k. [(n <= k) was pretty straight forward, but i couldnt solve it for (n > k)]. thanks :)
How I think
Try to divide the n object between two people such that their product is maximum. But there is one condition: if the total number of objects crosses k for any person, then the total number of objects of that person decreases by k.
Suppose you divide x, k group of objects and the number of objects remaining to distribute as rem.Now how to divide rem between two so that their multiple is maximum.
You can use one of the K groups again to maximize each person's total number of objects if it exists.
Hello CodeChef_admin, could you please take a look at my account? It's displaying an inactive status, but I haven't been inactive for this long. Also, there hasn't been an update on my ratings for yesterday, I managed to solve A, B, and E problems from Div2. Previously, I could see my updated rating, but now it's not showing, so kindly review my account. Thanks!
