Description
Given an array of positive integers nums, expand each integer into its individual digits (preserving their order) and return the resulting flat array, maintaining the original order of numbers in nums.
Example 1:
Input: nums = [13,25,83,77]
Output: [1,3,2,5,8,3,7,7]
Explanation:
- The separation of 13 is [1,3].
- The separation of 25 is [2,5].
- The separation of 83 is [8,3].
- The separation of 77 is [7,7].
answer = [1,3,2,5,8,3,7,7]. Note that answer contains the separations in the same order.
Example 2:
Input: nums = [7,1,3,9]
Output: [7,1,3,9]
Explanation: The separation of each integer in nums is itself.
answer = [7,1,3,9].
