* step 1: push all the information into a 5x5 square
* 	define a function group(i,j,k) that says at iteration k, cell i, j belongs to which group
* 	we want 25 groups at the end, group(i,j,k) is a function that roughly divides the grid into 25 roughly equal sized squares
* 
* step 2: divide the grid into 4 quadrants, each of size (n+1) by (n+1).
* 	for each quadrant, store the number of internal components, and the state of the border^ (row n and column n)
* 	store this at (0,0), (0,2), (2,0), (2,2) for each of the 4 quadrants respectively
* 
* step 3: on the 3x3 grid, 
*   decode the info at (0,0), (0,2), (2,0), (2,2)
* 	do more dfs on the row n and column n information to find the remaining components
* 	then add on the number on internal components in each quadrant
* 
* 
* ^ how to store the state of the border:
* 	we reserve 10 bits to store the number of internal components
* 	there are 2*n+1 <= 41 cells on the border --> 41 more bits
* 	the bits on the border, we divide them into consecutive groups
* 	observe the connectivity of the groups follows a bracket sequence
* 	for example, a b a c c a is (a_(b)_a_(c__c)a)
* 	store 1 bit for whether there is a open bracket before each group
* 	and 1 bit for whether there is a close bracket after
* 	max n+1 groups --> 2n+2 = 42 extra bits to store this info
