majority element
LeetCode题目, 题意:给定一个数组,该数组的主要元素是指的是总数超过数组一半的那个数。方法1:采用”分而治之”的方法,时间复杂度为O(NlogN)O(NlogN)主要思路是:左右两边通过递归求取主要元素后,判断是否相等,相等的话,直接返回该值,否则遍历判断两个元素那个是主要元素。static int majorityelem(vector& nums, int start, int...

leetcode——169 Majority Element(数组中出现次数过半的元素)
解题思路: (1)使用HashMap,Map的特点:不允许重复元素,因此在存储前需要判断是否存在 (2)判断HashMap中存在nums[i],如果存在,使用hm.get(nums[i])获取value,即通过key来获得value值,即count(出现的次数) (3)如果count大于数组长度的一般,即返回该元素 (4)如果count不满足条件,向HashMap存储元素以及出现的次数。...

Majority Element
需要注意的是:这道题只是要找出多数元素,已经默认存在多数元素了,而不需要去判断是否存在多数元素。之前的思路就一直卡在怎么判断多数元素存的的问题上了。思路解析:1. 初始化majorityIndex,并且维护其对应count;2. 遍历数组,如果下一个元素和当前候选元素相同,count加1,否则cou...
