Given an integer n. No-Zero integer is a positive integer which doesn’t contain any 0 in its decimal representation.

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]

Example 5:

1
2

Input: n = 1010
Output: [11,999]

Given an array nums. We define a running sum of an array as runningSum[i] = sum(nums[0]…nums[i]).

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:

1
2

Input: nums = [3,1,2,10,1]
Output: [3,4,6,16,17]

Given a column title as appear in an Excel sheet, return its corresponding column number.

For example:

A -> 1
B -> 2
C -> 3
...
Z -> 26
AA -> 27
AB -> 28 
...

Example 1:

1
2

Input: "A"
Output: 1

Example 2:

1
2

Input: "AB"
Output: 28

Example 3:

1
2

Input: "ZY"
Output: 701
