1317. Convert Integer to the Sum of Two No-Zero Integers
Problem Explanation
Explanation:
To solve this problem, we can start by iterating from 1 to n-1. For each number i, we check if both i and n-i do not contain any zero in their decimal representation. If we find such a pair, we return them as the result.
Algorithm:
- Iterate i from 1 to n-1.
- Check if both i and n-i do not contain any zero.
- If both conditions are satisfied, return [i, n-i].
Time Complexity:
The time complexity of this algorithm is O(n) where n is the given input integer.
Space Complexity:
The space complexity is O(1) as we are using constant space.

Solution Code
class Solution {
public int[] getNoZeroIntegers(int n) {
for (int i = 1; i < n; i++) {
if (isNoZero(i) && isNoZero(n - i)) {
return new int[]{i, n - i};
}
}
return new int[]{-1, -1}; // This should not be reached
}
private boolean isNoZero(int num) {
while (num > 0) {
if (num % 10 == 0) {
return false;
}
num /= 10;
}
return true;
}
