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 <= 1001 <= nums[i] <= 100
