"content": "<p>LeetCode company workers use key-cards to unlock office doors. Each time a worker uses their key-card, the security system saves the worker's name and the time when it was used. The system emits an <strong>alert</strong> if any worker uses the key-card <strong>three or more times</strong> in a one-hour period.</p>\n\n<p>You are given a list of strings <code>keyName</code> and <code>keyTime</code> where <code>[keyName[i], keyTime[i]]</code> corresponds to a person's name and the time when their key-card was used <strong>in a</strong> <strong>single day</strong>.</p>\n\n<p>Access times are given in the <strong>24-hour time format "HH:MM"</strong>, such as <code>"23:51"</code> and <code>"09:49"</code>.</p>\n\n<p>Return a <em>list of unique worker names who received an alert for frequent keycard use</em>. Sort the names in <strong>ascending order alphabetically</strong>.</p>\n\n<p>Notice that <code>"10:00"</code> - <code>"11:00"</code> is considered to be within a one-hour period, while <code>"22:51"</code> - <code>"23:52"</code> is not considered to be within a one-hour period.</p>\n\n<p> </p>\n<p><strong>Example 1:</strong></p>\n\n<pre>\n<strong>Input:</strong> keyName = ["daniel","daniel","daniel","luis","luis","luis","luis"], keyTime = ["10:00","10:40","11:00","09:00","11:00","13:00","15:00"]\n<strong>Output:</strong> ["daniel"]\n<strong>Explanation:</strong> "daniel" used the keycard 3 times in a one-hour period ("10:00","10:40", "11:00").\n</pre>\n\n<p><strong>Example 2:</strong></p>\n\n<pre>\n<strong>Input:</strong> keyName = ["alice","alice","alice","bob","bob","bob","bob"], keyTime = ["12:01","12:00","18:00","21:00","21:20","21:30","23:00"]\n<strong>Output:</strong> ["bob"]\n<strong>Explanation:</strong> "bob" used the keycard 3 times in a one-hour period ("21:00","21:20", "21:30").\n</pre>\n\n<p> </p>\n<p><strong>Constraints:</strong></p>\n\n<ul>\n\t<li><code>1 <= keyName.length, keyTime.length <= 10<sup>5</sup></code></li>\n\t<li><code>keyName.length == keyTime.length</code></li>\n\t<li><code>keyTime[i]</code> is in the format <strong>"HH:MM"</strong>.</li>\n\t<li><code>[keyName[i], keyTime[i]]</code> is <strong>unique</strong>.</li>\n\t<li><code>1 <= keyName[i].length <= 10</code></li>\n\t<li><code>keyName[i] contains only lowercase English letters.</code></li>\n</ul>\n",
