Problem Statement

Given two sorted arrays nums1 and nums2 containing integers only, return the smallest integer that appears in both arrays. If there isn't any integer that exists in both arrays, the function should return -1.

Examples

Example 1:

• input: nums1 = [1, 3, 5, 7], nums2 = [3, 4, 5, 6, 8, 10]
• expectedOutput: 3
• Justification: Both arrays share the integers 3 and 5, but the smallest common integer is 3.

Example 2:

• input: nums1 = [2, 4, 6], nums2 = [1, 3, 5]
• expectedOutput: -1
