If we select element at index i such that i + k + 1 >= N, then we cannot select any other element as part of the subsequence. Input : arr [] = {10, 100, 300, 200, 1000, 20, 30} k = 3 Output : 20 20 is the minimum possible difference between any maximum and minimum of any k numbers.

XOR, Copyright 2023 takeuforward | All rights reserved, I want to receive latest posts and interview tips, Top Array Interview Questions Structured Path with Video Solutions, Longest Subarray with sum K | [Postives and Negatives]. DFS If the element is equal to the target we return true else false. Then start traversing the array from its right end. A naive solution would be to cycle through all subsets of n numbers and, for every one of them, check if the subset sums to the right number. Binary Search Tree getline() Function and Character Array in C++, Write a program to reverse an array or string, Largest Sum Contiguous Subarray (Kadane's Algorithm). The first row dp[0][] indicates that only the first element of the array is considered, therefore for the target value equal to arr[0], only cell with that target will be true, so explicitly set dp[0][arr[0]] =true, (dp[0][arr[0]] means that we are considering the first element of the array with the target equal to the first element itself). Example 1: Input: nums = [1,1,1], k = 2 Output: 2 Example 2: Input: nums = [1,2,3], k = 3 Output: 2 Constraints: 1 <= nums.length <= 2 * 10 4 Find centralized, trusted content and collaborate around the technologies you use most. 565), Improving the copy in the close modal and post notices - 2023 edition, New blog post from our CEO Prashanth: Community is the future of AI. scanning array one by one. If you do allow adding a number to itself, then the second implementation could be simplified to: this function takes 2 parameters and loop through the length of list and inside the loop there is another loop which adds one number to other numbers in the list and check there sum if its equal to k or not. As usual, we would save all the prefix. Is a downhill scooter lighter than a downhill MTB with same performance? Can you select any other element in the subsequence? How do i find all subsequences whose sum lies between a to b efficiently? How to return 'True' if given number is the sum of two different number present in the list , in one pass only?
