电脑导购：假定电脑市场共有n家联想专卖店，按店的规模由大到小的顺序每家的坐标对应的是(xi,yi)，birdfly每天要接待m位客户，每次的客户坐标是(cx,cy)。对于每一位客户，birdfly要帮他们介绍好联想电脑的相关知识，并把他带到距离当前客户所在位置最近的一家联想店，距离按照dis=sqrt((x1-x2)^2+(y1-y2)^2)公式计算，要求输出m个客户中距离每一位客户坐标(cx,cy)最近的专卖店坐标(xi,yi)。-Computer shopping guide: Suppose there are n home PC market, Lenovo store, according to store size in descending order of the coordinates corresponding to each of the (xi, yi), birdfly m-bit reception a day to clients, each client coordinates is (cx, cy). For each customer, birdfly to help introduce them to think of a good knowledge of computers, and took him away from the current location of the nearest customer a Lenovo shop, according to the distance dis = sqrt ((x1-x2) ^ 2 (y1-y2) ^ 2) formula, the required output from the m customers each and every client coordinates (cx, cy) the nearest store coordinates (xi, yi).
