"content": "<p>Given an integer <code>n</code> and an integer array <code>rounds</code>. We have a circular track which consists of <code>n</code> sectors labeled from <code>1</code> to <code>n</code>. A marathon will be held on this track, the marathon consists of <code>m</code> rounds. The <code>i<sup>th</sup></code> round starts at sector <code>rounds[i - 1]</code> and ends at sector <code>rounds[i]</code>. For example, round 1 starts at sector <code>rounds[0]</code> and ends at sector <code>rounds[1]</code></p>\n\n<p>Return <em>an array of the most visited sectors</em> sorted in <strong>ascending</strong> order.</p>\n\n<p>Notice that you circulate the track in ascending order of sector numbers in the counter-clockwise direction (See the first example).</p>\n\n<p> </p>\n<p><strong class=\"example\">Example 1:</strong></p>\n<img alt=\"\" src=\"https://assets.leetcode.com/uploads/2020/08/14/tmp.jpg\" style=\"width: 433px; height: 341px;\" />\n<pre>\n<strong>Input:</strong> n = 4, rounds = [1,3,1,2]\n<strong>Output:</strong> [1,2]\n<strong>Explanation:</strong> The marathon starts at sector 1. The order of the visited sectors is as follows:\n1 --> 2 --> 3 (end of round 1) --> 4 --> 1 (end of round 2) --> 2 (end of round 3 and the marathon)\nWe can see that both sectors 1 and 2 are visited twice and they are the most visited sectors.
