Greedy Gift Givers

A group of NP (2 ≤ NP ≤ 10) uniquely named friends has decided to exchange gifts of money. Each of these friends might or might not give some money to any or all of the other friends. Likewise, each friend might or might not receive money from any or all of the other friends. Your goal in this problem is to deduce how much more money each person gives than they receive.

The rules for gift-giving are potentially different than you might expect. Each person sets aside a certain amount of money to give and divides this money evenly among all those to whom he or she is giving a gift. No fractional money is available, so dividing 3 among 2 friends would be 1 each for the friends with 1 left over -- that 1 left over stays in the giver's "account".

In any group of friends, some people are more giving than others (or at least may have more acquaintances) and some people have more money than others.

Given a group of friends, no one of whom has a name longer than 14 characters, the money each person in the group spends on gifts, and a (sub)list of friends to whom each person gives gifts, determine how much more (or less) each person in the group gives than they receive.

IMPORTANT NOTE

The grader machine is a Linux machine that uses standard Unix conventions: end of line is a single character often known as '\n'. This differs from Windows, which ends lines with two charcters, '\n' and '\r'. Do not let your program get trapped by this!

PROGRAM NAME: gift1

INPUT FORMAT

Line 1: The single integer, NP
Lines 2..NP+1: Each line contains the name of a group member
Lines NP+2..end: NP groups of lines organized like this:
The first line in the group tells the person's name who will be giving gifts.
The second line in the group contains two numbers: The initial amount of money (in the range 0..2000) to be divided up into gifts by the giver and then the number of people to whom the giver will give gifts, NGi (0 ≤ NGi ≤ NP-1).
If NGi is nonzero, each of the next NGi lines lists the the name of a recipient of a gift.

Problem 99 : Broken Necklace
http://fitzsimmons.ca/beads.html


파란색과 빨간색의 구슬로 이루어진 목걸이가 있다.
목걸이를 특정 지점에서 끊어서, 끊어진 목걸이의 양쪽 끝에서
다른 색의 구슬을 발견할 때 까지 구슬의 개수를 세어나간다.
그렇게해서 얻을 수 있는 최대의 구슬 개수를 찾는 것이 목표이다.
흰색 구슬이 나올 수도 있는데 이 구슬은 원하는 색으로 칠할 수 있다.

풀이 방식 :
목걸이의 구슬별로 잘라서 Circular Doubly Linked List로 만들고,
For 문을 돌려 각 구슬 별로 돌아가면서 해당 구슬을 기준으로 삼아서 목걸이를 끊고,
모든 경우를 고려하였다.
