nums1 and nums2, return the smallest number that contains at least one digit from each array.
Example 1:
Input: nums1 = [4,1,3], nums2 = [5,7] Output: 15 Explanation: The number 15 contains the digit 1 from nums1 and the digit 5 from nums2. It can be proven that 15 is the smallest number we can have.
Example 2:
Input: nums1 = [3,5,2,6], nums2 = [3,1,7] Output: 3 Explanation: The number 3 contains the digit 3 which exists in both arrays.
Constraints:
1 <= nums1.length, nums2.length <= 91 <= nums1[i], nums2[i] <= 9
