题目描述

给定两个字符串数组 username 和 website 和一个整数数组 timestamp 。给定的数组长度相同,其中元组 [username[i], website[i], timestamp[i]] 表示用户 username[i] 在时间 timestamp[i] 访问了网站 website[i] 。

访问模式 是包含三个网站的列表(不一定是完全不同的)。

  • 例如,["home", "away", "love"]["leetcode", "love", "leetcode"],和 ["luffy", "luffy", "luffy"] 都是模式。

一种 访问模式得分 是访问该模式中所有网站的用户数量,这些网站在该模式中出现的顺序相同。

  • 例如,如果模式是 [“home”,“away”,“love”] ,那么分数就是用户数量 x , x 访问了 “home” ,然后访问了 “away” ,然后访问了 “love”
  • 同样,如果模式是 ["leetcode", "love", "leetcode"] ,那么分数就是用户数量 x ,使得 x 访问了"leetcode",然后访问了 "love" ,之后又访问了 "leetcode"
  • 另外,如果模式是 [“luffy”,“luffy”,“luffy”] ,那么分数就是用户数量 x ,这样 x 就可以在不同的时间戳上访问 “luffy” 三次。

返回 得分 最大的 访问模式 。如果有多个访问模式具有相同的最大分数,则返回字典序最小的。

 

示例 1:

输入:username = ["joe","joe","joe","james","james","james","james","mary","mary","mary"], timestamp = [1,2,3,4,5,6,7,8,9,10], website = ["home","about","career","home","cart","maps","home","home","about","career"]
输出:["home","about","career"]
解释:本例中的元组是:
["joe","home",1],["joe","about",2],["joe","career",3],["james","home",4],["james","cart",5],["james","maps",6],["james","home",7],["mary","home",8],["mary","about",9], and ["mary","career",10].
模式("home", "about", "career") has score 2 (joe and mary).
模式("home", "cart", "maps") 的得分为 1 (james).
模式 ("home", "cart", "home") 的得分为 1 (james).
模式 ("home", "maps", "home") 的得分为 1 (james).
模式 ("cart", "maps", "home") 的得分为 1 (james).
模式 ("home", "home", "home") 的得分为 0(没有用户访问过home 3次)。

示例 2:

输入: username = ["ua","ua","ua","ub","ub","ub"], timestamp = [1,2,3,4,5,6], website = ["a","b","a","a","b","c"]
输出: ["a","b","a"]

 

提示:

  • 3 <= username.length <= 50
  • 1 <= username[i].length <= 10
  • timestamp.length == username.length
  • 1 <= timestamp[i] <= 109
  • website.length == username.length
  • 1 <= website[i].length <= 10
  • username[i] 和 website[i] 都只含小写字符
  • 它保证至少有一个用户访问了至少三个网站
  • 所有元组 [username[i], timestamp[i], website[i] 均 不重复
