Hey! Can anybody help me with a solution to this? We have an array of pairs [ (x1,y1) , (x2,y2), ... , (xn,yn) ]. Initially, we are at the coordinates (0,0). We can use whatever pair from the array (maximum one time) to move from the actual position (a,b) where we are to (x + xi, y + yi). The numbers from the array's pair are between [-10^4, +10^4]. Which is the maximum distance we can move from the origin (0,0) after using some of these pairs from the array? We have a maximum of 2000 pairs. I am grateful to those who brighten me.
