Given an integer array of size n, find all elements that appear more than ? n/3 ? times. The algorithm should run in linear time and in O(1) space.
Hint:

1.跟让求一个数组中出现次数超过一半的元素类似,这次让求出现次数超过n/3次数的元素,原则上是类似的,但难度要大好多
2.因为是类似的,所以总体思路应该还是一样的,但具体怎么做呢?这次维护一个curNum1和curNum2两个锚点并用count1和count2来计算锚点出现的次数,因为求超过n/3次数的元素,所以数组中可能存在两个这样的元素,其它的就和Majority Element类似了,只有nums[i]与curNum1和curNum2均不相等时才会count1--,count2--
3.和Majori...

一个数据序列的主元素,是指序列中出现次数超过序列长度一半的元素。法1(期望时间复杂度为O(n)):由于主元素出现次数超过序列长度的一半,因此,主元素一定是中位数。可以利用递归划分求中位数的方法,期望时间复杂度为O(n)。法2:显然,如果一个序列存在主元素,那么我们去掉序列中不同的两个数,剩下序列的主...
