Separate the Digits in an Array
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]The separations are [1, 3], [2, 5], [8, 3], and [7, 7], concatenated in the same order.
Example 2
Input
nums = [7,1,3,9]Output
[7,1,3,9]The separation of each integer in
nums is itself, so the answer is unchanged.Constraints
- 1 <= nums.length <= 1000
- 1 <= nums[i] <= 10^5
