{ "data": { "question": { "questionId": "2469", "questionFrontendId": "2389", "categoryTitle": "Algorithms", "boundTopicId": 1774484, "title": "Longest Subsequence With Limited Sum", "titleSlug": "longest-subsequence-with-limited-sum", "content": "

You are given an integer array nums of length n, and an integer array queries of length m.

\n\n

Return an array answer of length m where answer[i] is the maximum size of a subsequence that you can take from nums such that the sum of its elements is less than or equal to queries[i].

\n\n

A subsequence is an array that can be derived from another array by deleting some or no elements without changing the order of the remaining elements.

\n\n

 

\n

Example 1:

\n\n
\nInput: nums = [4,5,2,1], queries = [3,10,21]\nOutput: [2,3,4]\nExplanation: We answer the queries as follows:\n- The subsequence [2,1] has a sum less than or equal to 3. It can be proven that 2 is the maximum size of such a subsequence, so answer[0] = 2.\n- The subsequence [4,5,1] has a sum less than or equal to 10. It can be proven that 3 is the maximum size of such a subsequence, so answer[1] = 3.\n- The subsequence [4,5,2,1] has a sum less than or equal to 21. It can be proven that 4 is the maximum size of such a subsequence, so answer[2] = 4.\n
\n\n

Example 2:

\n\n
\nInput: nums = [2,3,4,5], queries = [1]\nOutput: [0]\nExplanation: The empty subsequence is the only subsequence that has a sum less than or equal to 1, so answer[0] = 0.

\n\n\n", "translatedTitle": "和有限的最长子序列", "translatedContent": "

给你一个长度为 n 的整数数组 nums ,和一个长度为 m 的整数数组 queries

\n\n

返回一个长度为 m 的数组 answer ,其中 answer[i] nums 元素之和小于等于 queries[i]子序列最大 长度 

\n\n

子序列 是由一个数组删除某些元素(也可以不删除)但不改变剩余元素顺序得到的一个数组。

\n\n

 

\n\n

示例 1:

\n\n
\n输入:nums = [4,5,2,1], queries = [3,10,21]\n输出:[2,3,4]\n解释:queries 对应的 answer 如下:\n- 子序列 [2,1] 的和小于或等于 3 。可以证明满足题目要求的子序列的最大长度是 2 ,所以 answer[0] = 2 。\n- 子序列 [4,5,1] 的和小于或等于 10 。可以证明满足题目要求的子序列的最大长度是 3 ,所以 answer[1] = 3 。\n- 子序列 [4,5,2,1] 的和小于或等于 21 。可以证明满足题目要求的子序列的最大长度是 4 ,所以 answer[2] = 4 。\n
\n\n

示例 2:

\n\n
\n输入:nums = [2,3,4,5], queries = [1]\n输出:[0]\n解释:空子序列是唯一一个满足元素和小于或等于 1 的子序列,所以 answer[0] = 0 。
