2540\. Minimum Common Value

Easy

Given two integer arrays `nums1` and `nums2`, sorted in non-decreasing order, return _the **minimum integer common** to both arrays_. If there is no common integer amongst `nums1` and `nums2`, return `-1`.

Note that an integer is said to be **common** to `nums1` and `nums2` if both arrays have **at least one** occurrence of that integer.

**Example 1:**

**Input:** nums1 = [1,2,3], nums2 = [2,4]

**Output:** 2

**Explanation:** The smallest element common to both arrays is 2, so we return 2.

**Example 2:**

**Input:** nums1 = [1,2,3,6], nums2 = [2,3,4,5]

**Output:** 2

**Explanation:** There are two common elements in the array 2 and 3 out of which 2 is the smallest, so 2 is returned.

**Constraints:**

*   1 <= nums1.length, nums2.length <= 105
*   1 <= nums1[i], nums2[j] <= 109
*   Both `nums1` and `nums2` are sorted in **non-decreasing** order.
