{ "data": { "question": { "questionId": "1562", "questionFrontendId": "1452", "categoryTitle": "Algorithms", "boundTopicId": 247875, "title": "People Whose List of Favorite Companies Is Not a Subset of Another List", "titleSlug": "people-whose-list-of-favorite-companies-is-not-a-subset-of-another-list", "content": "

Given the array favoriteCompanies where favoriteCompanies[i] is the list of favorites companies for the ith person (indexed from 0).

\n\n

Return the indices of people whose list of favorite companies is not a subset of any other list of favorites companies. You must return the indices in increasing order.

\n\n

 

\n

Example 1:

\n\n
\nInput: favoriteCompanies = [["leetcode","google","facebook"],["google","microsoft"],["google","facebook"],["google"],["amazon"]]\nOutput: [0,1,4] \nExplanation: \nPerson with index=2 has favoriteCompanies[2]=["google","facebook"] which is a subset of favoriteCompanies[0]=["leetcode","google","facebook"] corresponding to the person with index 0. \nPerson with index=3 has favoriteCompanies[3]=["google"] which is a subset of favoriteCompanies[0]=["leetcode","google","facebook"] and favoriteCompanies[1]=["google","microsoft"]. \nOther lists of favorite companies are not a subset of another list, therefore, the answer is [0,1,4].\n
\n\n

Example 2:

\n\n
\nInput: favoriteCompanies = [["leetcode","google","facebook"],["leetcode","amazon"],["facebook","google"]]\nOutput: [0,1] \nExplanation: In this case favoriteCompanies[2]=["facebook","google"] is a subset of favoriteCompanies[0]=["leetcode","google","facebook"], therefore, the answer is [0,1].\n
\n\n

Example 3:

\n\n
\nInput: favoriteCompanies = [["leetcode"],["google"],["facebook"],["amazon"]]\nOutput: [0,1,2,3]\n

Constraints:

\n\n\n", "translatedTitle": "收藏清单", "translatedContent": "

给你一个数组 favoriteCompanies ，其中 favoriteCompanies[i] 是第 i 名用户收藏的公司清单（下标从 0 开始）。

\n\n

请找出不是其他任何人收藏的公司清单的子集的收藏清单，并返回该清单下标。下标需要按升序排列。

\n\n

 

\n\n

示例 1：

\n\n
输入：favoriteCompanies = [["leetcode","google","facebook"],["google","microsoft"],["google","facebook"],["google"],["amazon"]]\n输出：[0,1,4] \n解释：\nfavoriteCompanies[2]=["google","facebook"] 是 favoriteCompanies[0]=["leetcode","google","facebook"] 的子集。\nfavoriteCompanies[3]=["google"] 是 favoriteCompanies[0]=["leetcode","google","facebook"] 和 favoriteCompanies[1]=["google","microsoft"] 的子集。\n其余的收藏清单均不是其他任何人收藏的公司清单的子集，因此，答案为 [0,1,4] 。\n
\n\n

示例 2：

\n\n
输入：favoriteCompanies = [["leetcode","google","facebook"],["leetcode","amazon"],["facebook","google"]]\n输出：[0,1] \n解释：favoriteCompanies[2]=["facebook","google"] 是 favoriteCompanies[0]=["leetcode","google","facebook"] 的子集，因此，答案为 [0,1] 。\n
\n\n

示例 3：

\n\n
输入：favoriteCompanies = [["leetcode"],["google"],["facebook"],["amazon"]]\n输出：[0,1,2,3]\n
