Problem
Return the distance between (x1, y1) and (x2, y2) as an int: sqrt omitted — return (x2-x1)^2 + (y2-y1)^2.
Examples
distance(0, 0, 3, 4) -> 25distance(1, 1, 1, 1) -> 0
Return the distance between (x1, y1) and (x2, y2) as an int: sqrt omitted — return (x2-x1)^2 + (y2-y1)^2.
distance(0, 0, 3, 4) -> 25distance(1, 1, 1, 1) -> 0
