Python: Find the majority element from a given array of size n using Collections module

Python Collections: Exercise-17 with Solution

Write a Python program to find the majority element from a given array of size n using Collections module.

Note: The majority element algorithm finds a majority element, if there is one: that is, an element that occurs repeatedly for more than half of the elements of the input.

Sample Solution:

Python Code:

import collections
class Solution(object):
    def majorityElement(self, nums):
        """
        :type nums: List[int]
        :return type: int
        """
        count_ele=collections.Counter(nums)
        return count_ele.most_common()[0][0]

result = Solution().majorityElement([10,10,20,30,40,10,20,10])
print(result)

Sample Output:

10

Python: Tips of the Day

Use Reversed() In for Loops:

>>> tasks = ['laundry', 'picking up kids', 'gardening', 'cooking']
>>> for task in reversed(tasks):
...     print(task)
... 
cooking
