times.
You may assume that the array is non-empty and the majority element always exist in the array.

public class Solution {
public int majorityElement(int[] nums) {
int candidate = 0;
int count = 0;
for(int i=0;i<nums.length;i++)
{
if(count == 0)
{
candidate = nums[i];
count = 1;
}
else
{
if(nums[i] == candidate)
count++;
else
count--;
}
}
return candidate;
}
}
