<p>You are given an integer <code>n</code> representing the number of players in a game and a 2D array <code>pick</code> where <code>pick[i] = [x<sub>i</sub>, y<sub>i</sub>]</code> represents that the player <code>x<sub>i</sub></code> picked a ball of color <code>y<sub>i</sub></code>.</p>
|
||
|
|
|
||
|
|
<p>Player <code>i</code> <strong>wins</strong> the game if they pick <strong>strictly more</strong> than <code>i</code> balls of the <strong>same</strong> color. In other words,</p>

|
<ul>
|
||
|
|
<li>Player 0 wins if they pick any ball.</li>
|
||
|
|
<li>Player 1 wins if they pick at least two balls of the <em>same</em> color.</li>
|
||
|
|
<li>...</li>
|
||
|
|
<li>Player <code>i</code> wins if they pick at least<code>i + 1</code> balls of the <em>same</em> color.</li>
