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 。
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。
使用时间的格式是 24小时制 ,形如 "HH:MM" ,比方说 "23:51" 和 "09:49" 。
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。
请注意 "10:00" - "11:00" 视为一个小时时间范围内,而 "23:51" - "00:10" 不被视为一小时内,因为系统记录的是某一天内的使用情况。
示例 1:
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"]
输出:["daniel"]
解释:"daniel" 在一小时内使用了 3 次员工卡("10:00","10:40","11:00")。
示例 2:
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"]
输出:["bob"]
解释:"bob" 在一小时内使用了 3 次员工卡("21:00","21:20","21:30")。
示例 3:
输入:keyName = ["john","john","john"], keyTime = ["23:58","23:59","00:01"]
输出:[]
示例 4:
输入:keyName = ["leslie","leslie","leslie","clare","clare","clare","clare"], keyTime = ["13:00","13:20","14:00","18:00","18:51","19:30","19:49"]
输出:["clare","leslie"]
提示:
1 <= keyName.length, keyTime.length <= 105
keyName.length == keyTime.length
keyTime 格式为 "HH:MM" 。
保证 [keyName[i], keyTime[i]] 形成的二元对 互不相同 。
1 <= keyName[i].length <= 10
keyName[i] 只包含小写英文字母。
