Problem:
Given an array of size n, find the majority element. The majority element is the element that appears more than ⌊ n/2 ⌋ times.
You may assume that the array is non-empty and the majority element always exist in the array.
A possible solution:
class Solution {
public:
int majorityElement(vector<int>& nums) {
int majority;
int cnt=0;
for(int i=0;i<nums.size();i++)
{
if(cnt == 0)
{
majority = nums[i];
cnt ++;
}
else
{
majority == nums[i]?cnt++:cnt--;
if(cnt>nums.size()/2+1) return majority;
}
}
return majority;
}
};
