Topics: Mid Level , Array , Simulation , Biweekly Contest 97

Given an array of positive integers nums , return an array answer that consists of the digits of each integer in nums after separating them in the same order they appear in nums .

To separate the digits of an integer is to get all the digits it has in the same order.

For example, for the integer 10921 , the separation of its digits is [1,0,9,2,1] .

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].…
