<p>You are given an integer array <code>nums</code>. Two players are playing a game with this array: player 1 and player 2.</p>
|
|
|
|
<p>Player 1 and player 2 take turns, with player 1 starting first. Both players start the game with a score of <code>0</code>. At each turn, the player takes one of the numbers from either end of the array (i.e., <code>nums[0]</code> or <code>nums[nums.length - 1]</code>) which reduces the size of the array by <code>1</code>. The player adds the chosen number to their score. The game ends when there are no more elements in the array.</p>
|
|
|
|
<p>Return <code>true</code> if Player 1 can win the game. If the scores of both players are equal, then player 1 is still the winner, and you should also return <code>true</code>. You may assume that both players are playing optimally.</p>

|
<p><strong>Example 1:</strong></p>
|
|
|
|
<pre>
|
|
<strong>Input:</strong> nums = [1,5,2]
|
|
<strong>Output:</strong> false
|
|
<strong>Explanation:</strong> Initially, player 1 can choose between 1 and 2.
|
|
If he chooses 2 (or 1), then player 2 can choose from 1 (or 2) and 5. If player 2 chooses 5, then player 1 will be left with 1 (or 2).
|
|
So, final score of player 1 is 1 + 2 = 3, and player 2 is 5.
|
|
Hence, player 1 will never be the winner and you need to return false.
|
|

|
|
<p><strong>Example 2:</strong></p>
|
|
|
|
<pre>
|
|
<strong>Input:</strong> nums = [1,5,233,7]
|
|
<strong>Output:</strong> true
|
|
<strong>Explanation:</strong> Player 1 first chooses 1. Then player 2 has to choose between 5 and 7. No matter which number player 2 choose, player 1 can choose 233.
|
|
Finally, player 1 has more score (234) than player 2 (12), so you need to return True representing player1 can win.

<p><strong>Constraints:</strong></p>
|
|
|
|
<ul>
|
|
<li><code>1 <= nums.length <= 20</code></li>
|
|
<li><code>0 <= nums[i] <= 10<sup>7</sup></code></li>
