1999. Smallest Greater Multiple Made of Two Digits

https://leetcode.com/problems/smallest-greater-multiple-made-of-two-digits

Description

Given three integers, k, digit1, and digit2, you want to find the smallest integer that is:

• Larger than k,

• A multiple of k, and

• Comprised of only the digits digit1 and/or digit2.

Return the smallest such integer. If no such integer exists or the integer exceeds the limit of a signed 32-bit integer (231 - 1), return -1.

Example 1:

**Input:** k = 2, digit1 = 0, digit2 = 2
**Output:** 20
**Explanation:**
20 is the first integer larger than 2, a multiple of 2, and comprised of only the digits 0 and/or 2.

Example 2:

**Input:** k = 3, digit1 = 4, digit2 = 2
**Output:** 24
**Explanation:**
24 is the first integer larger than 3, a multiple of 3, and comprised of only the digits 4 and/or 2.

Example 3:

**Input:** k = 2, digit1 = 0, digit2 = 0
**Output:** -1
**Explanation:**No integer meets the requirements so return -1.

Constraints:

• 1 <= k <= 1000

• 0 <= digit1 <= 9

• 0 <= digit2 <= 9
