Codeforces Round 1056 (Div. 2) Solutions for Problems A through D
Problem A – The Simple Tournament
We can derive a direct formula: The total number of matches is always 2n - 2. The reasoning: from the winners' bracket, n - 1 teams drop to the losers' bracket, from which n - 2 teams are eliminated, leaving two teams that play one final match. Alternatively, a straightforward simulation also works.

Simple Graph Theory and Construction
A
Consider vertices with weight 2 as adding one to vertices with weight 1. Thus the problem is split into two parts: constructing the tree and adding one to vertices.
In the first part, constructing the tree as balanced as possible is beneficial, as will be shown in the second step.
Construction:
Process DFS ...

Problem A - 4
Question
With (n) horizontal lines and (m) vertical lines drawn on a plane, how many axis-aligned rectangles are formed that contain no interior lines?
Solution
Consider each dimension independent.
Along any straight line, (n) distinct points partition the line into (n - 1) segments. These segments serve as the edges of our rectan ...
