Convert Integer to the Sum of Two No-Zero Integers - Math - Easy - LeetCode

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:

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:

Input: n = 11 Output: [2,9] Example 3:

Input: n = 10000 Output: [1,9999] Example 4:

Input: n = 69 Output: [1,68] Example 5:

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

Constraints:

2 <= n <= 10^4

public class Solution {
 public int[] GetNoZeroIntegers(int n) {
 var ans = new int[2];
 if(n==0){
 return ans;
 }
 
 for(int i=1;i<n;i++){
 if(NotContainsZero(i)&&NotContainsZero(n-i)){
 ans[0]=i;
 ans[1]=n-i;
 return ans;
 }
 }
 return ans;
 }
 
 private bool NotContainsZero(int num){
 if(num==0){
 return false;
 }
 while(num>0){
 if(num%10==0){
 return false;
 }
 num/=10;
 }
 return true;
 }
}

Time complexity: O(n * log10(n)) Space complexity: O(1)
