문제

주식회사 월드에서는 오랫동안 열심히 일을 하면 그에 따라 승진할 수도 있고, 그만큼 많은 급료를 받을 수도 있다.

즉, 어떤 사원의 상사는 적어도 그 사원만큼은 회사에서 근무한 것이고, 그 사원보다 많은 급료를 받는다. 또, 어느 사원의 직속 상사는, 적어도 그 사원만큼 회사에서 근무했고, 그 사원보다 많은 급료를 받는 사람들 중에서 가장 적은 급료를 받는 사람이다.

어느 사원의 직속 상사에게 있어서, 그 사원은 부하가 된다. 어떤 사원의 부하의 부하들도 모두 그 사원의 부하라 하자. 만약에 어느 사원이 누구의 상사도 아니면 그 사원은 부하가 없다.

주식회사 월드의 상사-부하 관계가 위와 같이 정의될 때, 몇몇 사원의 직속 상사와 부하의 수를 구하는 프로그램을 작성하시오.

입력

첫째 줄에 두 정수 n(1 ≤ n ≤ 30,000), m(1 ≤ m ≤ 200)이 주어진다. n은 사원의 수고, m은 우리가 직속 상사와 부하의 수를 알아보려는 사원의 수이다. 다음 n개의 줄에는 각 사원의 정보를 나타내는 세 정수 a, b, c가 주어진다. a(1 ≤ a ≤ 2,147,483,647)는 사원의 ID, b(0 ≤ b ≤ 10,000,000)는 급료, c(1,000,000 ≤ c ≤ 2,500,000)는 근무한 시간(분 단위)을 나타낸다. 사원의 ID는 중복되지 않는다.

다음 m개의 줄에는 직속 상사와 부하의 수를 알아보려는 사원의 ID가 주어진다. 사원의 정보로 주어진 사원의 ID만 주어진다.

출력

m개의 줄에 입력된 순서대로 해당 사원의 직속 상사의 ID와 부하의 수를 출력한다. 만약 입력으로 주어진 ID가 사장일 경우, 즉 가장 오래 근무하였고 가장 많은 급료를 받는 사원의 ID일 경우에는 직속 상사의 ID 대신에 0을 출력한다.

At TALL Enterprises Inc. this &ldquo;de facto standard&rdquo; has been properly formalized: your boss is always at least as tall as you are. Furthermore, you can safely assume that your boss earns a bit more than you do. In fact, you can be absolutely sure that your immediate boss is the person who earns the least among all the employees that earn more than you and are at least as tall as you are. Furthermore, if you are the immediate boss of someone, that person is your subordinate, and all his subordinates are your subordinates as well. If you are nobody&rsquo;s boss, then you have no subordinates. As simple as these rules are, many people working for TALL are unsure of to whom they should be turning in their weekly progress report and how many subordinates they have. Write a program that will help in determining for any employee who the immediate boss of that employee is and how many subordinates they have. Quality Assurance at TALL have devised a series of tests to ensure that your program is correct. These test are described below.<\/p>\r\n","input":"<p>On the first line of the input is a single positive integer n, telling the number of test scenarios to follow. Each scenario begins with a line containing two positive integers m and q, where m (at most 30000) is the number of employees and q (at most 200) is the number of queries. The following m lines each list an employee by three integers on the same line: employee ID number (six decimal digits, the first one of which is not zero), yearly salary in Euros and finally height in &micro;m (1 &micro;m = 10-6 meters &ndash; accuracy is important at TALL). The chairperson is the employee that earns more than anyone else and is also the tallest person in the company. Then there are q lines listing queries. Each query is a single legal employee ID.<\/p>\r\n\r\n<p>The salary is a positive integer which is at most 10 000 000. No two employees have the same ID, and no two employees have the same salary. The height of an employee is at least 1 000 000 &micro;m and at most 2 500 000 &micro;m.<\/p>\r\n","output":"<p>For each employee ID x in a query output a single line with two integers y k, separated by one space character, where y is the ID of x&rsquo;s boss, and k is the number of subordinates of x. If the query is the ID of the chairperson, then you should output 0 as the ID of his or her boss (since the chairperson has no immediate boss except, possibly, God).<\/p>\r\n","hint":"","original":"1","html_title":"0","problem_lang_tcode":"English"}]
