{ "data": { "question": { "questionId": "2179", "questionFrontendId": "2070", "categoryTitle": "Algorithms", "boundTopicId": 1096006, "title": "Most Beautiful Item for Each Query", "titleSlug": "most-beautiful-item-for-each-query", "content": "
You are given a 2D integer array items
where items[i] = [pricei, beautyi]
denotes the price and beauty of an item respectively.
You are also given a 0-indexed integer array queries
. For each queries[j]
, you want to determine the maximum beauty of an item whose price is less than or equal to queries[j]
. If no such item exists, then the answer to this query is 0
.
Return an array answer
of the same length as queries
where answer[j]
is the answer to the jth
query.
\n
Example 1:
\n\n\nInput: items = [[1,2],[3,2],[2,4],[5,6],[3,5]], queries = [1,2,3,4,5,6]\nOutput: [2,4,5,5,6,6]\nExplanation:\n- For queries[0]=1, [1,2] is the only item which has price <= 1. Hence, the answer for this query is 2.\n- For queries[1]=2, the items which can be considered are [1,2] and [2,4]. \n The maximum beauty among them is 4.\n- For queries[2]=3 and queries[3]=4, the items which can be considered are [1,2], [3,2], [2,4], and [3,5].\n The maximum beauty among them is 5.\n- For queries[4]=5 and queries[5]=6, all items can be considered.\n Hence, the answer for them is the maximum beauty of all items, i.e., 6.\n\n\n
Example 2:
\n\n\nInput: items = [[1,2],[1,2],[1,3],[1,4]], queries = [1]\nOutput: [4]\nExplanation: \nThe price of every item is equal to 1, so we choose the item with the maximum beauty 4. \nNote that multiple items can have the same price and/or beauty. \n\n\n
Example 3:
\n\n\nInput: items = [[10,1000]], queries = [5]\nOutput: [0]\nExplanation:\nNo item has a price less than or equal to 5, so no item can be chosen.\nHence, the answer to the query is 0.\n\n\n
\n
Constraints:
\n\n1 <= items.length, queries.length <= 105
items[i].length == 2
1 <= pricei, beautyi, queries[j] <= 109
给你一个二维整数数组 items
,其中 items[i] = [pricei, beautyi]
分别表示每一个物品的 价格 和 美丽值 。
同时给你一个下标从 0 开始的整数数组 queries
。对于每个查询 queries[j]
,你想求出价格小于等于 queries[j]
的物品中,最大的美丽值 是多少。如果不存在符合条件的物品,那么查询的结果为 0
。
请你返回一个长度与 queries
相同的数组 answer
,其中 answer[j]
是第 j
个查询的答案。
\n\n
示例 1:
\n\n输入:items = [[1,2],[3,2],[2,4],[5,6],[3,5]], queries = [1,2,3,4,5,6]\n输出:[2,4,5,5,6,6]\n解释:\n- queries[0]=1 ,[1,2] 是唯一价格 <= 1 的物品。所以这个查询的答案为 2 。\n- queries[1]=2 ,符合条件的物品有 [1,2] 和 [2,4] 。\n 它们中的最大美丽值为 4 。\n- queries[2]=3 和 queries[3]=4 ,符合条件的物品都为 [1,2] ,[3,2] ,[2,4] 和 [3,5] 。\n 它们中的最大美丽值为 5 。\n- queries[4]=5 和 queries[5]=6 ,所有物品都符合条件。\n 所以,答案为所有物品中的最大美丽值,为 6 。\n\n\n
示例 2:
\n\n输入:items = [[1,2],[1,2],[1,3],[1,4]], queries = [1]\n输出:[4]\n解释:\n每个物品的价格均为 1 ,所以我们选择最大美丽值 4 。\n注意,多个物品可能有相同的价格和美丽值。\n\n\n
示例 3:
\n\n输入:items = [[10,1000]], queries = [5]\n输出:[0]\n解释:\n没有物品的价格小于等于 5 ,所以没有物品可以选择。\n因此,查询的结果为 0 。\n\n\n
\n\n
提示:
\n\n1 <= items.length, queries.length <= 105
items[i].length == 2
1 <= pricei, beautyi, queries[j] <= 109
