Majority Element using Python

The majority element problem is one of the popular coding interview questions. Here we need to find the element that appears more than the other element in an array. So, if you want to know how to solve this problem, this article is for you. In this article, I will take you through how to solve the majority element problem using Python.

Majority Element using Python

In the majority element problem, you will be given an array of integers containing a majority element that appears more than [n / 2] times. To solve this problem, we need to return the value of the majority element. For example, look at the input and output of this problem below:

Input: [2,2,1,1,1,2,2]
Output: 2

In the above example, 2 appears more than 1, so 2 is the majority element.

I hope you have understood what the majority element problem means. Now, below is how you can solve this problem using the Python programming language:

def majorityElement(nums):
    count = 0
    major_element = 0
    for i in nums:
        if count == 0:
            major_element = i
        if major_element == i:
            count = count + 1
        else:
            count = count - 1
    return major_element

nums = [2,2,1,1,1,2,2]
print(majorityElement(nums))
        
Output: 2
