( 482 ) | D | Tiles for Bathroom | PROGRAMMING | two pointers | 2900 |
B"Kostya is extremely busy: he is renovating his house! He needs to hand wallpaper, assemble furniture throw away trash. Kostya is buying tiles for bathroom today. He is standing in front of a large square stand with tiles in a shop. The stand is a square of n x n cells, each cell of which contains a small tile with color c_{i, ,j} . The shop sells tiles in packs: more specifically, you can only buy a subsquare of the initial square. A subsquare is any square part of the stand, i. e. any set S(i_0, j_0, k) = {c_{i, ,j} | i_0 <= i < i_0 + k, j_0 <= j < j_0 + k } with 1 <= i_0, j_0 <= n - k + 1 . Kostya still does not know how many tiles he needs, so he considers the subsquares of all possible sizes. He doesn't want his bathroom to be too colorful. Help Kostya to count for each k <= n the number of subsquares of size k x k that have at most q different colors of tiles. Two subsquares are considered different if their location on the stand is different. The first line contains two integers n and q ( 1 <= n <= 1500 , 1 <= q <= 10 ) -- the size of the stand and the limit on the number of distinct colors in a subsquare. Each of the next n lines contains n integers c_{i, ,j} ( 1 <= c_{i, ,j} <= n^2 ): the j -th integer in the i -th line is the color of the tile in the cell (i, ,j) . For each k from 1 to n print a single integer -- the number of subsquares of size k x k with no more than q different colors. In the first example all colors are distinct. Kostya doesn't want the subsquare have more than 4 colors, so he can buy any subsquare of size 1 x 1 or 2 x 2 , but he can't buy a subsquare of size 3 x 3 . In the second example there are colors that appear multiple times. Because q = 8 , Kostya can buy any subsquare of size 1 x 1 and 2 x 2 , and"... |
