On each turn, we choose the <strong>heaviest two stones</strong> and smash them together. Suppose the heaviest two stones have weights <code>x</code> and <code>y</code> with <code>x &lt;= y</code>. The result of this smash is:</p>\n\n<ul>\n\t<li>If <code>x == y</code>, both stones are destroyed, and</li>\n\t<li>If <code>x != y</code>, the stone of weight <code>x</code> is destroyed, and the stone of weight <code>y</code> has new weight <code>y - x</code>.</li>\n</ul>\n\n<p>At the end of the game, there is <strong>at most one</strong> stone left.</p>\n\n<p>Return <em>the smallest possible weight of the left stone</em>. If there are no stones left, return <code>0</code>.</p>\n\n<p>&nbsp;</p>\n<p><strong>Example 1:</strong></p>\n\n<pre>\n<strong>Input:</strong> stones = [2,7,4,1,8,1]\n<strong>Output:</strong> 1\n<strong>Explanation:</strong> \nWe combine 7 and 8 to get 1 so the array converts to [2,4,1,1,1] then,\nwe combine 2 and 4 to get 2 so the array converts to [2,1,1,1] then,\nwe combine 2 and 1 to get 1 so the array converts to [1,1,1] then,\nwe combine 1 and 1 to get 0 so the array converts to [1] then that&#39;s the value of the last stone.\n</pre>\n\n<p><strong>Example 2:</strong></p>\n\n<pre>\n<strong>Input:</strong> stones = [1]\n<strong>Output:</strong> 1\n</pre>\n\n<p>&nbsp;</p>\n<p><strong>Constraints:</strong></p>\n\n<ul>\n\t<li><code>1 &lt;= stones.length &lt;= 30</code></li>\n\t<li><code>1 &lt;= stones[i] &lt;= 1000</code></li>\n</ul>\n",
