Think recursively

#

you dont use recursion here

#

There is an approach but its kinda long because it requires 4 pointers

#

You can easily use recursion to solve this problem

#

By shrinking the 4 corners everytime

#

@tiny wave recursion isnt optimal

#

because youll be using extra space

#

You can solve the problem recursively, but do the process iteratively

#

Think recursively, but maybe use a while loop to solve it

#

Its basically simulation

#

Hint: use one while loop inside 4 loops for 4 sides
