Seg 2D problem: Query using manhattan distance[HELP]

Правка en3, от ThomazL, 2017-05-31 04:43:42

Hi guys,

Today i viewed a, aparently, simple seg2D problem:

SET x y d: Set position (x,y) of the grid to integer d.

QUERY x y d: Return the gcd (Greatest Common Divisor) of all positions of the grid that are at most 'd' positions away (Manhattan Distance) from position (x,y).

But i have no ideia to solve this query type '-'

Can someone help me?
