Solution Description :

Ad hoc problem

If Arif position (x,y)
Then 5 escape positions for Arif are (x,y) (x-1,y) (x+1,y) (x,y-1) (x,y+1)

Now check each position of other programmer
-----Suppose the programmer position is (Xi,Yi)
-----If Xi is match any first value of escape position then the cell is block. i.e. if Xi=x-1 then cell (x-1,y) is block.
-----If Yi is match any second value of escape position then the cell is block. i.e. if Yi=y+1 then cell (x,y+1) is block.

At last is all 5 escape position (cell) are block then print "Party time! Let's find a restaurant!"
Otherwise print "Escaped again! More 2D grid problems!"
