{ "data": { "question": { "questionId": "1709", "questionFrontendId": "1604", "categoryTitle": "Algorithms", "boundTopicId": 433886, "title": "Alert Using Same Key-Card Three or More Times in a One Hour Period", "titleSlug": "alert-using-same-key-card-three-or-more-times-in-a-one-hour-period", "content": "

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 alert if any worker uses the key-card three or more times in a one-hour period.

\n\n

You are given a list of strings keyName and keyTime where [keyName[i], keyTime[i]] corresponds to a person's name and the time when their key-card was used in a single day.

\n\n

Access times are given in the 24-hour time format "HH:MM", such as "23:51" and "09:49".

\n\n

Return a list of unique worker names who received an alert for frequent keycard use. Sort the names in ascending order alphabetically.

\n\n

Notice that "10:00" - "11:00" is considered to be within a one-hour period, while "22:51" - "23:52" is not considered to be within a one-hour period.

\n\n

 

\n

Example 1:

\n\n
\nInput: keyName = ["daniel","daniel","daniel","luis","luis","luis","luis"], keyTime = ["10:00","10:40","11:00","09:00","11:00","13:00","15:00"]\nOutput: ["daniel"]\nExplanation: "daniel" used the keycard 3 times in a one-hour period ("10:00","10:40", "11:00").\n
\n\n

Example 2:

\n\n
\nInput: keyName = ["alice","alice","alice","bob","bob","bob","bob"], keyTime = ["12:01","12:00","18:00","21:00","21:20","21:30","23:00"]\nOutput: ["bob"]\nExplanation: "bob" used the keycard 3 times in a one-hour period ("21:00","21:20", "21:30").\n

Constraints:

\n\n\n", "translatedTitle": "警告一小时内使用相同员工卡大于等于三次的人", "translatedContent": "

力扣公司的员工都使用员工卡来开办公室的门。每当一个员工使用一次他的员工卡，安保系统会记录下员工的名字和使用时间。如果一个员工在一小时时间内使用员工卡的次数大于等于三次，这个系统会自动发布一个 警告 。

\n\n

给你字符串数组 keyName 和 keyTime ，其中 [keyName[i], keyTime[i]] 对应一个人的名字和他在 某一天 内使用员工卡的时间。

\n\n

使用时间的格式是 24小时制 ，形如 \"HH:MM\" ，比方说 \"23:51\" 和 \"09:49\" 。

\n\n

请你返回去重后的收到系统警告的员工名字，将它们按 字典序升序 排序后返回。

\n\n

请注意 \"10:00\" - \"11:00\" 视为一个小时时间范围内，而 \"22:51\" - \"23:52\" 不被视为一小时时间范围内。

\n\n

示例 1：

\n\n
\n输入：keyName = [\"daniel\",\"daniel\",\"daniel\",\"luis\",\"luis\",\"luis\",\"luis\"], keyTime = [\"10:00\",\"10:40\",\"11:00\",\"09:00\",\"11:00\",\"13:00\",\"15:00\"]\n输出：[\"daniel\"]\n解释：\"daniel\" 在一小时内使用了 3 次员工卡（\"10:00\"，\"10:40\"，\"11:00\"）。\n
\n\n

示例 2：

\n\n
\n输入：keyName = [\"alice\",\"alice\",\"alice\",\"bob\",\"bob\",\"bob\",\"bob\"], keyTime = [\"12:01\",\"12:00\",\"18:00\",\"21:00\",\"21:20\",\"21:30\",\"23:00\"]\n输出：[\"bob\"]\n解释：\"bob\" 在一小时内使用了 3 次员工卡（\"21:00\"，\"21:20\"，\"21:30\"）。\n
