3697. Compute Decimal Representation
Description
You are given a positive integer n.
A positive integer is a base-10 component if it is the product of a single digit from 1 to 9 and a non-negative power of 10. For example, 500, 30, and 7 are base-10 components, while 537, 102, and 11 are not.
Express n as a sum of only base-10 components, using the fewest base-10 components possible.
Return an array containing these base-10 components in descending order.
Example 1:
Input: n = 537
Output: [500,30,7]
Explanation:
We can express 537 as 500 + 30 + 7. It is impossible to express 537 as a sum using fewer than 3 base-10 components.
Example 2:
Input: n = 102
Output: [100,2]
Explanation:
We can express 102 as 100 + 2. 102 is not a base-10 component, which means 2 base-10 components are needed.
Example 3:
Input: n = 6
Output: [6]
Explanation:
6 is a base-10 component.
Constraints:
1 <= n <= 109
