Come Looking for the Smallest Num Which Must Be > Than a Specific Num. 🔎

🔥 FULLTIME

To solve this problem, you gonna need to write up the func in the editor 👉

What you've been given: int Z

What your func is gonna do:

1. find the smallest num that is > than Z.

2. total of all the digits of the num you find must == 2 * (total of all digits of Z)

Memo 📝:

When solving this problem, you can mainly focus on correctness. As for your code performance, it would not be the focus this time 😉.

Example 1:

Input:  N = 10
Output: 11 
Explanation:
As we can see, 11 is the smallest num that is > 10.

What is the total sum of all digits of 10? The ans is 1 + 0 = 1...

What is the total sum of all digits of 11? The ans is 1 + 1 = 2...

2 == 1 * 2, so 11 should be returned.

Example 2:

Input:  N = 14
Output: 19 
Explanation:
The total of all the digits of 19 (1 + 9 = 10) == 2 * total of digits of 14 (1 + 4 = 5)

Example 3:

Input:  N = 99
Output: 9999 
Explanation:
The sum of digits of 9999 (9 + 9 + 9 + 9 = 36) == total of digits of 99 (9 + 9 = 18).

Constraints:

1 <= Z <= 500.
