The last time I posted a post "know a little about recent points (ask questions)", I will discuss this issue further today. Last time, it was implemented based on the MapX control. Today, it is implemented based on text files instead of MapX.Problem Review: if the point P (latitude and longitude) is known, the nearest vertex D (point, line, and surface) is found. The name of D is returned, and the direction, position, and distance between D and P are returned, the total number of features is gre

Topic:Given an array S of n integers, find three integers in S such so the sum is closest to a give n number, target. Return the sum of the three integers. You may assume this each input would has exactly one solution. For example, given array S = {-1 2 1-4}, and target = 1. The sum is closest to the target is 2. (-1 + 2 + 1 = 2).Translation: Given an array of nums integers, and a goal and target, find t
