You are given two non-negative integers n and s.
Return the largest integer that has at most n digits and whose sum of digits is s. If no such integer exists, return -1.
Example 1:
Input: n = 2, s = 9
Output: 90
Explanation:
The largest integer with at most 2 digits that has a sum of digits of 9 is 90.
Example 2:
Input: n = 2, s = 19
Output: -1
Explanation:
There is no integer with at most 2 digits that has a sum of digits of 19, so the answer is -1.
Example 3:
Input: n = 5, s = 0
Output: 0
Explanation:
The only non-negative integer whose digits sum to 0 is 0.
Constraints:
1 <= n <= 50 <= s <= 100Loading editor...
