Longest Subarray With Maximum Bitwise And
Longest Subarray With Maximum Bitwise AndSo here is the example of the given problem β. The problem is actually asking for the longest subarray with all values = max(nums) The maximum possible bitwise AND is the maximum number in nums, in order to have a subarray with the maximum possible bitwise AND the subarray can only contain the maximum number otherwise the bitwise AND will decrease. The longest subarray with that value is [3,3], so we return 2. π΄ πππ«π: Maximum XOR With an Element From Array β here. Example 1: Input: nums = [1,3,8,48,10] Output: 3 Explanation: The longest nice subarray is [3,8,48]. Test case 4: It is optimal to take the subarray. If the array contains all non-positive numbers, then a solution is any subarray of size 1 containing the maximal value of the array (or the empty subarray, if it is permitted).
