1. Abridged Problem Statement
Given N teams (numbered 1…N, your team is 1), each has current wins w[i], total remaining games r[i], and for every pair (i, j) the number of their remaining head-to-head games cnt[i][j]. Each remaining game produces exactly one win. Decide whether it's possible to assign outcomes of all remaining games so that team 1 finishes with at least as many wins as every other team. Print "YES" if it's possible, otherwise "NO."

2. Detailed Editorial
We face the classical "baseball elimination" problem. Team 1's maximum possible wins is
 W1_max = w[1] + r[1].
We must check if we can distribute the wins of all remaining games among the other teams so none exceed W1_max. Games involving team 1 can trivially be "given" to team 1 (or lost), but games between other teams require consistent assignment.

We build a flow network to model this:

 1. Compute W1_max.
 2. For each opponent i = 2…N:
    - If w[i] > W1_max already, answer NO immediately.
    - We will enforce that i's final wins ≤ W1_max by bounding its extra wins to (W1_max − w[i]).
 3. Create a source node S and sink T.
 4. For every pair of distinct opponents i<j, let g = cnt[i][j]:
    - Create a "game node" G_{i,j}.
    - Add an edge (S → G_{i,j}) with capacity = g, representing all these games.
    - Add edges (G_{i,j} → i) and (G_{i,j} → j), each with capacity = g, so each game's single win goes to either team i or team j.
    - Sum these g values as total_games.
 5. For each opponent i = 2…N, add edge (i → T) with capacity = (W1_max − w[i]), limiting additional wins they can take.
 6. Compute max flow from S to T.
    - If max_flow = total_games, we can assign every head-to-head game between opponents without making anyone exceed W1_max. Hence answer YES.
    - Otherwise NO.

Complexity: There are O(N^2) game nodes and O(N^2) edges; using Dinic runs comfortably for N≤20.

5. Compressed Editorial
Compute team 1's max possible wins W1. Build a flow network: source→each opponent-vs-opponent game node (capacity = number of games), game node→its two teams (capacity same), and each opponent team→sink (capacity = W1 − current wins of that team). If the max flow equals total inter-opponent games, answer YES; else NO.
