{ "data": { "question": { "questionId": "2498", "questionFrontendId": "2411", "categoryTitle": "Algorithms", "boundTopicId": 1827366, "title": "Smallest Subarrays With Maximum Bitwise OR", "titleSlug": "smallest-subarrays-with-maximum-bitwise-or", "content": "

You are given a 0-indexed array nums of length n, consisting of non-negative integers. For each index i from 0 to n - 1, you must determine the size of the minimum sized non-empty subarray of nums starting at i (inclusive) that has the maximum possible bitwise OR.

\n\n\n\n

The bitwise OR of an array is the bitwise OR of all the numbers in it.

\n\n

Return an integer array answer of size n where answer[i] is the length of the minimum sized subarray starting at i with maximum bitwise OR.

\n\n

A subarray is a contiguous non-empty sequence of elements within an array.

\n\n

 

\n

Example 1:

\n\n
\nInput: nums = [1,0,2,1,3]\nOutput: [3,3,2,2,1]\nExplanation:\nThe maximum possible bitwise OR starting at any index is 3. \n- Starting at index 0, the shortest subarray that yields it is [1,0,2].\n- Starting at index 1, the shortest subarray that yields the maximum bitwise OR is [0,2,1].\n- Starting at index 2, the shortest subarray that yields the maximum bitwise OR is [2,1].\n- Starting at index 3, the shortest subarray that yields the maximum bitwise OR is [1,3].\n- Starting at index 4, the shortest subarray that yields the maximum bitwise OR is [3].\nTherefore, we return [3,3,2,2,1]. \n
\n\n

Example 2:

\n\n
\nInput: nums = [1,2]\nOutput: [2,1]\nExplanation:\nStarting at index 0, the shortest subarray that yields the maximum bitwise OR is of length 2.\nStarting at index 1, the shortest subarray that yields the maximum bitwise OR is of length 1.\nTherefore, we return [2,1].\n

\n\n\n", "translatedTitle": "按位或最大的最小子数组长度", "translatedContent": "

给你一个长度为 n 下标从 0 开始的数组 nums ，数组中所有数字均为非负整数。对于 0 到 n - 1 之间的每一个下标 i ，你需要找出 nums 中一个 最小 非空子数组，它的起始位置为 i （包含这个位置），同时有 最大 的 按位或运算值 。

\n\n\n\n

一个数组的按位或运算值是这个数组里所有数字按位或运算的结果。

\n\n

请你返回一个大小为 n 的整数数组 answer，其中 answer[i]是开始位置为 i ，按位或运算结果最大，且 最短 子数组的长度。

\n\n

子数组 是数组里一段连续非空元素组成的序列。

\n\n

 

\n\n

示例 1：

\n\n
输入：nums = [1,0,2,1,3]\n输出：[3,3,2,2,1]\n解释：\n任何位置开始，最大按位或运算的结果都是 3 。\n- 下标 0 处，能得到结果 3 的最短子数组是 [1,0,2] 。\n- 下标 1 处，能得到结果 3 的最短子数组是 [0,2,1] 。\n- 下标 2 处，能得到结果 3 的最短子数组是 [2,1] 。\n- 下标 3 处，能得到结果 3 的最短子数组是 [1,3] 。\n- 下标 4 处，能得到结果 3 的最短子数组是 [3] 。\n所以我们返回 [3,3,2,2,1] 。\n
\n\n

示例 2：

\n\n
输入：nums = [1,2]\n输出：[2,1]\n解释：\n下标 0 处，能得到最大按位或运算值的最短子数组长度为 2 。\n下标 1 处，能得到最大按位或运算值的最短子数组长度为 1 。\n所以我们返回 [2,1] 。\n
