and 3 has been written at points (1,1), (2,0), and (3, 1) respectively and this
pattern has continued.
You are to write a
program that reads the coordinates of a point (x, y), and writes the number (if
any) that has been written at that point. (x, y) coordinates in the input are in
the range 0...5000.
