Q14 The thunderstоrm nоt оnly destroyed power, it аlso interrupted network connections within cаmpus. To help n students prepаre their exams, the university IT department decides to place n portable Wi-Fi routers around the campus. Let b_1, b_2, ..., b_n be the locations of n portable Wi-Fi routers. Also let s_1, ..., s_n be the locations of these students. Due to budget constraints, these Wi-Fi routers are pretty weak: each of them can connect to only one device, and can service a distance at most D. Q14 Part 1 Describe an algorithm that can quickly determine whether or not all students can get connected to Wi-Fi, given the location b_1, ..., b_n, s_1, ..., s_n, and the parameters D. (Hint: try to reduce this problem to the bipartite matching problem.)
