In a deck of cards, each card has an integer written on it. Return true if and only if you can choose X >= 2 such that it is possible to split the entire deck into 1 or more groups of cards, where: Each group has exactly X cards. All the cards in eac…

给定一副牌,每张牌上都写着一个整数. 此时,你需要选定一个数字 X,使我们可以将整副牌按下述规则分成 1 组或更多组: 每组都有 X 张牌. 组内所有的牌上都写着相同的整数. 仅当你可选的 X >= 2 时返回 true. 示例 1: 输入:[1,2,3,4,4,3,2,1] 输出:true 解释:可行的分组是 [1,1],[2,2],[3,3],[4,4] 示例 2: 输入:[1,1,1,2,2,2,3,3] 输出:false 解释:没有满足要求的分组. 示例 3: 输入:[1] 输出:fal…
