本题目给出的射击比赛的规则非常简单，谁打的弹洞距离靶心最近，谁就是冠军；谁差得最远，谁就是菜鸟。本题给出一系列弹洞的平面坐标(x,y)，请你编写程序找出冠军和菜鸟。我们假设靶心在原点(0,0)。 输入格式： 输入在第一行中给出一个正整数 N（≤ 10 000）。随后 N 行，每行按下列格式给出： ID x y 其中ID是运动员的编号（由 4 位数字组成）；x和y是其打出的弹洞的平面坐标(x,y)，均为整数，且 0 ≤ |x|, |y| ≤ 100。题目保证每个运动员的编号不重复，且每人只打 1 枪。 输出格式： 输出冠军和菜鸟的编号，中间空 1 格。题目保证他们是唯一的。 输入样例：

本题要求你帮助某网站的用户注册模块写一个密码合法性检查的小功能。该网站要求用户设置的密码必须由不少于6个字符组成，并且只能有英文字母、数字和小数点.，还必须既有字母也有数字。 输入格式： 输入第一行给出一个正整数 N（≤ 100），随后 N 行，每行给出一个用户设置的密码，为不超过 80 个字符的非空字符串，以回车结束。 输出格式： 对每个用户的密码，在一行中输出系统反馈信息，分以下5种： * 如果密码合法，输出Your password is wan mei.； * 如果密码太短，不论合法与否，都输出Your password is tai duan le.； * 如果密码长度合

The task of this problem is simple: insert a sequence of distinct positive integers into a hash table first. Then try to find another sequence of integer keys from the table and output the average search time (the number of comparisons made to find whether or not the key is in the table). The hash f

This is a problem given in the Graduate Entrance Exam in 2018: Which of the following is NOT a topological order obtained from the given directed graph? Now you are supposed to write a program to test each of the options. Input Specification: Each input file contains one test case. For each case

In computer science, aheapis a specialized tree-based data structure that satisfies the heap property: if P is a parent node of C, then the key (the value) of P is either greater than or equal to (in a max heap) or less than or equal to (in a min heap) the key of C. A common implementation of a heap

Given a collection of number segments, you are supposed to recover the smallest number from them. For example, given {32, 321, 3214, 0229, 87}, we can recover many numbers such like 32-321-3214-0229-87 or 0229-32-87-321-3214 with respect to different orders of combinations of these segments, and the

One way that the police finds the head of a gang is to check people’s phone calls. If there is a phone call between A and B, we say that A and B is related. The weight of a relation is defined to be the total time length of all the phone calls made between the two persons. A “Gang” is a cluster of m

Shopping in Mars is quite a different experience. The Mars people pay by chained diamonds. Each diamond has a value (in Mars dollars M$). When making the payment, the chain can be cut at any position for only once and some of the diamonds are taken off the chain one by one. Once a diamond is off the

This time, you are supposed to help us collect the data for family-owned property. Given each person’s family members, and the estate（房产）info under his/her own name, we need to know the size of each family, and the average area and number of sets of their real estate. Input Specification: Each inp

Eva loves to collect coins from all over the universe, including some other planets like Mars. One day she visited a universal shopping mall which could accept all kinds of coins as payments. However, there was a special requirement of the payment: for each bill, she must pay the exact amount. Since
