You are given a number. Your task is to check if there exists a permutation of the digits of this number which is divisible by 4.
Example 1:
Input: 003 Output: 1Explanation: For 003, we have a permutation
300 which is divisible by 4.
Example 2:
Input:
123456
Output:
1Explanation:
For 123456, we have 123564 which is a
permutation of 123456 and is divisible by 4.
Your Task:
You don't need to read input or print anything. Your task is to complete the function divisible_by_four() which takes string as input parameter and returns 1 if any permutaion of string is divisible by 4 otherwise returns 0.
Expected Time Complexity: O(N^2) Expected Auxiliary Space: O(1)

Avoid using static/global variables in your code as your code is tested
against multiple test cases and these tend to retain their previous values.
Passing the Sample/Custom Test cases does not guarantee the correctness of code.
On submission, your code is tested against multiple test cases consisting of all
possible corner cases and stress constraints.
