European Girls' Olympiad in Informatics: 2023 Day 1 Problem 2
There are participants numbered
to
competing in a padel tournament held over
days. Exactly one match is held each day. There are
medals handed out in the tournament, a new one for each match. In the match on day
, the two participants numbered
and
are participating. The following happens in the match:
- Participant
beats participant
.
- A new medal is given to the winner
.
- All of the loser's current medals are given to the winner.
On day (the day after the last match), the prize ceremony is held. At the ceremony, all medals are collected, and then each medal is given to the participant that held that medal the longest. Formally, medal
is given to the participant who held medal
for the most nights (not necessarily in a row), as of day
. If two or more participants have held a medal for the same number of nights, the medal is given to the participant with the smallest index among them.
Your goal is to determine how many medals each participant is awarded at the prize ceremony.
Input Specification
The first line of input contains the integers and
, the number of participants and the number of matches.
Then lines follow. The
th of these lines contains two integers
and
, the participants competing on day
, where participant
beats participant
.
Output Specification
On the single line of output print integers, the
th number denoting the number of medals that participant
has after the prize ceremony.

Your solution will be tested on a set of test groups, each worth a number of points. Each test group contains a set of test cases. To get the points for a test group you need to solve all test cases in the test group.
Group | Score | Limits |
---|---|---|
1 | 12 | |
2 | 16 | |
3 | 15 | The winner of the |
4 | 20 | At the time of the |
5 | 22 | Once a participant loses, they are never in a match again. |
6 | 15 | No additional constraints |
Example
For the first sample test case, the following illustration shows who held which medals throughout the tournament. When participant 1 loses on the 3rd day, all her medals are given to participant 2.
The second sample can be seen below.
After the prize ceremony, participant 0 is given medals 5 and 6, participant 1 is given medals 3 and 4, and participant 2 is given medals 0, 1 and 2.
