'''
Write a function to check if a list is balanced or not.
Instructions
A list is considered balanced if the sum of the first half of the list is equal to the sum of the second half.

input:[1, 2, 3, 3, 2, 1]
output:True
Reason: The sum of the first half [1, 2, 3] is 6 and the sum of the second half [3, 2, 1] is also 6.

Input:[1, 2, 3, 4, 5]
Output:False

Input:[2, 2, 2, 2]
Output:True
