904 - Fruit Into Baskets.<p>Medium</p>
<p>You are visiting a farm that has a single row of fruit trees arranged from left to right. The trees are represented by an integer array <code>fruits</code> where <code>fruits[i]</code> is the <strong>type</strong> of fruit the <code>i<sup>th</sup></code> tree produces.</p>
<p>You want to collect as much fruit as possible. However, the owner has some strict rules that you must follow:</p>
<ul>
<li>You only have <strong>two</strong> baskets, and each basket can only hold a <strong>single type</strong> of fruit. There is no limit on the amount of fruit each basket can hold.</li>
<li>Starting from any tree of your choice, you must pick <strong>exactly one fruit</strong> from <strong>every</strong> tree (including the start tree) while moving to the right. The picked fruits must fit in one of your baskets.</li>
<li>Once you reach a tree with fruit that cannot fit in your baskets, you must stop.</li>
</ul>
<p>Given the integer array <code>fruits</code>, return <em>the <strong>maximum</strong> number of fruits you can pick</em>.</p>
<p><strong>Example 1:</strong></p>
<p><strong>Input:</strong> fruits = [1,2,1]</p>
<p><strong>Output:</strong> 3</p>
<p><strong>Explanation:</strong> We can pick from all 3 trees.</p>
<p><strong>Example 2:</strong></p>
<p><strong>Input:</strong> fruits = [0,1,2,2]</p>
<p><strong>Output:</strong> 3</p>
<p><strong>Explanation:</strong> We can pick from trees [1,2,2]. If we had started at the first tree, we would only pick from trees [0,1].</p>
<p><strong>Example 3:</strong></p>
<p><strong>Input:</strong> fruits = [1,2,3,2,2]</p>
<p><strong>Output:</strong> 4</p>
<p><strong>Explanation:</strong> We can pick from trees [2,3,2,2]. If we had started at the first tree, we would only pick from trees [1,2].</p>
<p><strong>Constraints:</strong></p>
<ul>
<li><code>1 <= fruits.length <= 10<sup>5</sup></code></li>
<li><code>0 <= fruits[i] < fruits.length</code></li>
</ul>
