+3688\. Bitwise OR of Even Numbers in an Array
+
+Easy
+
+You are given an integer array `nums`.
+
+Return the bitwise **OR** of all **even** numbers in the array.
+
+If there are no even numbers in `nums`, return 0.
+
+**Example 1:**
+
+**Input:** nums = [1,2,3,4,5,6]
+
+**Output:** 6
+
+**Explanation:**
+
+The even numbers are 2, 4, and 6. Their bitwise OR equals 6.
+
+**Example 2:**
+
+**Input:** nums = [7,9,11]
+
+**Output:** 0
+
+**Explanation:**
+
+There are no even numbers, so the result is 0.
+
+**Example 3:**
+
+**Input:** nums = [1,8,16]
+
+**Output:** 24
+
+**Explanation:**
+
+The even numbers are 8 and 16. Their bitwise OR equals 24.
+
+**Constraints:**
+
+*   `1 <= nums.length <= 100`
+*   `1 <= nums[i] <= 100`
