Given an arrayarr. You can choose a set of integers and remove all the occurrences of these integers in the array. Returnthe minimum size of the setso that at least half of the integers of the array are removed. 样例: 限制: 个人思路: 先一个字典统计所有的字符出现的个数,然后按照从大到...
Explanation: Choosing {3,7} will make the new array [5,5,5,2,2] which has size 5 (i.e equal to half of the size of the old array). Possible sets of size 2 are {3,5},{3,2},{5,2}. Choosing set {2,7} is not possible as it will make the new array [3,3,3,3,5,5...
