WebMar 12, 2024 · Subarray with given sum is: 1 9. 3 7. Time Complexity: O (n^2 + n), because we need to generate all possible subarrays. This contributes O (n^2) and printing the subarray takes O (n). As a result, O (n^2 + n) ~ O (n^2). Space Complexity: O (1), we are not using any extra space. WebApr 14, 2024 · 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. Example 1: Input: nums = [4,5,2,1], queries = [3,10,21] Output: [2,3,4] Explanation: We answer the queries as follows: The subsequence [2,1] has a sum less than or equal to 3.
