Modify logs 1 This version modifies the software coordinate conversion algorithm. The position information of the secondary radar monitoring data is expressed in polar coordinates, which is determined by the distance from the target to the radar, the azimuth, and the air pressure height measured by the aircraft. In the display, You need to convert the polar coordinate data to the WGS-84 coordinate system, t

[Description ]: Given n small islands and their locations, and entering the radar radiation area, how many radar stations are required to cover all small islands? [Train of Thought Analysis ]: The first thing that comes to mind in this question is the use of greedy algorithms, but how can we get greedy? When I started to solve this problem, I had only one idea: to make every
