Given an array of positive integers nums, return an array containing the digits of each integer in nums, separated and ordered as they appear in the original array.

Separating the digits of an integer means extracting its individual digits in their original order from left to right.

Constraints:

• $1 \leq$ nums.length $\leq 1000$

• $1 \leq$ nums[i] $\leq 10^5$
