<p>You are given an array <code>prices</code> where <code>prices[i]</code> is the price of a given stock on the <code>i<sup>th</sup></code> day.</p>
|
|
|
|
<p>You want to maximize your profit by choosing a <strong>single day</strong> to buy one stock and choosing a <strong>different day in the future</strong> to sell that stock.</p>
|
|
|
|
<p>Return <em>the maximum profit you can achieve from this transaction</em>. If you cannot achieve any profit, return <code>0</code>.</p>
|
|
|
|
<p> </p>
|
|
<p><strong>Example 1:</strong></p>
|
|
|
|
<pre>
|
|
<strong>Input:</strong> prices = [7,1,5,3,6,4]
|
|
<strong>Output:</strong> 5
|
|
<strong>Explanation:</strong> Buy on day 2 (price = 1) and sell on day 5 (price = 6), profit = 6-1 = 5.
|
|
Note that buying on day 2 and selling on day 1 is not allowed because you must buy before you sell.

|
</pre>
|
|
|
|
<p><strong>Example 2:</strong></p>
|
|
|
|
<pre>
|
|
<strong>Input:</strong> prices = [7,6,4,3,1]
|
|
<strong>Output:</strong> 0
|
|
<strong>Explanation:</strong> In this case, no transactions are done and the max profit = 0.
