{ "data": { "question": { "questionId": "3381", "questionFrontendId": "3095", "boundTopicId": null, "title": "Shortest Subarray With OR at Least K I", "titleSlug": "shortest-subarray-with-or-at-least-k-i", "content": "
You are given an array nums
of non-negative integers and an integer k
.
An array is called special if the bitwise OR
of all of its elements is at least k
.
Return the length of the shortest special non-empty subarray of nums
, or return -1
if no special subarray exists.
\n
Example 1:
\n\nInput: nums = [1,2,3], k = 2
\n\nOutput: 1
\n\nExplanation:
\n\nThe subarray [3]
has OR
value of 3
. Hence, we return 1
.
Example 2:
\n\nInput: nums = [2,1,8], k = 10
\n\nOutput: 3
\n\nExplanation:
\n\nThe subarray [2,1,8]
has OR
value of 11
. Hence, we return 3
.
Example 3:
\n\nInput: nums = [1,2], k = 0
\n\nOutput: 1
\n\nExplanation:
\n\nThe subarray [1]
has OR
value of 1
. Hence, we return 1
.
\n
Constraints:
\n\n1 <= nums.length <= 50
0 <= nums[i] <= 50
0 <= k < 64
