Return a list of two integers [A, B] where:

A and B are No-Zero integers.
A + B = n
It’s guarateed that there is at least one valid solution. If there are many valid solutions you can return any of them.

Example 1:

1
2
3
Input: n = 2
Output: [1,1]
Explanation: A = 1, B = 1. A + B = n and both A and B don't contain any 0 in their decimal representation.

Example 2:

1
2
Input: n = 11
Output: [2,9]

Example 3:

1
2
Input: n = 10000
Output: [1,9999]

Example 4:

1
2
Input: n = 69
Output: [1,68]

Return the running sum of nums.

Example 1:

1
2
3
Input: nums = [1,2,3,4]
Output: [1,3,6,10]
Explanation: Running sum is obtained as follows: [1, 1+2, 1+2+3, 1+2+3+4].

Example 2:

1
2
3
Input: nums = [1,1,1,1,1]
Output: [1,2,3,4,5]
Explanation: Running sum is obtained as follows: [1, 1+1, 1+1+1, 1+1+1+1, 1+1+1+1+1].

Example 3:
