Minimum Euclidean Distance

Given a set of points in the two-dimensional plane, your task is to find the minimum Euclidean distance between two distinct points. The Euclidean distance of points (x_1,y_1) and (x_2,y_2) is \sqrt{(x_1-x_2)^2+(y_1-y_2)^2}. Input The first input line has an integer n: the number of points. After this, there are n lines that describe the points. Each line has two integers x and y. You may assu
