Given an array arr of size n and an integer x. Find if there's a triplet in the array which sums up to the given integer x. Examples Input:n = 6, x = 13, arr[] = [1,4,45,6,10,8] Output: 1 Explanation: The triplet {1, 4, 8} in the array sums up to 13
Given an array A[] of N integers and an integer X. The task is to find the sum of three integers in A[] such that it is closest to X. Example 1: Input: N = 4 A[] = {-1 , 2, 1, -4} X = 1 Output: 2 Explaination: Sums
Given an array, arr of integers, and another number target, find three integers in the array such that their sum is closest to the target. Return the sum of the three integers. Note: If there are multiple solutions, return the maximum one. Examples :

METHOD 3. Use a Map/Set. Finally, you can also solve the problem using a Map/Set. You just need to iterate through the array, fix the first element, and then try to find the other two elements using the approach similar to the two sum problem.. I’m using a Set in the following solution instead of a Map as used in the two-sum problem because in the two-sum problem, we had to keep track of the index of the elements as well. But In this problem, we just care about the element and not its index.
Given arrays of different sizes, find the number of distinct triplets where is an element of , written as , , and , satisfying the criteria: .. For example, given and , we find four distinct triplets: .. Function Description. Complete the triplets function in the editor below. It must return the number of distinct triplets that can be formed from the given arrays.
Oct 17, 2023 · Complexity Analysis: Time complexity: O(N^2), There are only two nested loops traversing the array, so time complexity is O(n^2). Two pointers algorithm takes O(n) time and the first element can be fixed using another nested traversal. Auxiliary Space: O(1), As no extra space is required. Triplet Sum in Array (3sum) using Hashing: This approach uses extra space but is simpler than the two-pointers approach.
May 31, 2022 · Practice this problem. The problem is a standard variation of the 3SUM problem, where instead of looking for numbers whose sum is 0, we look for numbers whose sum is any constant C.. 1. Naive Recursive Approach. The idea is similar to the 0–1 Knapsack problem and uses recursion.We either consider the current item or exclude it and recur for the remaining elements for each item.
