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]. 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].
Constraints:
1 <= nums.length <= 1000
1 <= nums[i] <= 10^5
