The distance between two points $(x_0,y_0)$ $(x_{0}, y_{0})$ and $(x_1,y_1)$ $(x_{1}, y_{1})$ on a coordinate grid is $\sqrt{(x_1-x_0)^2+(y_1-y_0)^2}$ $\sqrt{(x_{1} - x_{0})^{2} + (y_{1} - y_{0})^{2}}$ . We can apply this formula to the distance between the agents and the shady person, and check if it's less than or equal to $D$ $D$ .

Time Complexity: $\mathcal O(1)$ $O (1)$
