For query 2, L=8 and R=12. There are 10 subsets with sum of their elements as 8, 13 subsets with sum of their elements as 9, 12 subsets with sum of their elements as 10, 14 subsets with sum of their elements as 11 and 14 subsets with sum of their elements as 12. So, the answer to the query is 10 + 13 + 12 + 14 + 14 = 63 mod (\(10^9\) +7) = 63. I am working on this problem: The Subset Sum problem takes as input a set X = {x1, x2 ,…, xn} of n integers and another integer K.The problem is to check if there exists a subset X' of X whose elements sum to K and finds the subset if there's any. In the NP problem the unit length of the x's increases exponentially with N.That is why the dynamic programming solutions are not a polynomial time solution to the NP Subset Sum problem. That being the case, there are still practical instances of the Subset Sum problem where the x's are bounded and the dynamic programming solution is valid.

Constraints: $$1 \le N \le 10^5$$ $$-10^9 \le A_i \le 10^9$$ We define subsequence as any subset of an array. We define a subarray as a contiguous subsequence in an array. Given an array, find the maximum possible sum among: all nonempty subsequences. Print the two values as space-separated integers on one line. Note that empty subarrays/subsequences should not be considered. This is similar to the subset sum problem, where you are required to find a subset whom sum is a value k.. Since there is a solution to your problem (you have a subset S whom multiplication is k) if and only if you have a subset of log(x) for each x in the set, whom sum is log(k) (the same subset, with log on each element), the problems are pretty much identical.

That being the case, there are still practical instances of the Subset Sum problem where the x's are bounded and the dynamic programming solution is valid. Print Subset Sum to K. Given an array A and an integer K, print all subsets of A which sum to K. Subsets are of length varying from 0 to n, that contain elements of the array. But the order of elements should remain same as in the input array. Note : The order of subsets are not important. Just print them in different lines. We define subsequence as any subset of an array. We define a subarray as a contiguous subsequence in an array. Given an array, find the maximum possible sum among: all nonempty subsequences. Print the two values as space-separated integers on one line. Note that empty subarrays/subsequences should not be considered. The naive method is to run two loops. The outer loop picks the beginning element, the inner loop finds the maximum possible sum with first element picked by outer loop and compares this maximum with the overall maximum. Finally return the overall maximum. The time complexity of the Naive method is O (n^2). Using Divide and Conquer approach, we ...

The sum of an array is the sum of its elements. Given an element array of integers, , and an integer, , determine the maximum value of the sum of any of its subarrays modulo . For example, Assume and . The following table lists all subarrays and their moduli: In this problem, there is a given set with some integer elements. And another some value is also provided, we have to find a subset of the given set whose sum is the same as the given sum value. Here backtracking approach is used for trying to select a valid subset when an item is not valid, we will backtrack to get the previous subset and add ... Subset sum problem hackerearth (source: on YouTube) Subset sum problem hackerearth ... This is similar to the subset sum problem, where you are required to find a subset whom sum is a value k..

HackerRank Solutions Over the course of the next few (actually many) days, I will be posting the solutions to previous Hacker Rank challenges. The page is a good start for people to solve these problems as the time constraints are rather forgiving. Maximum sum such that no two elements are adjacent Given an array of positive numbers, find the maximum sum of a subsequence with the constraint that no 2 numbers in the sequence should be adjacent in the array. Let's take a problem, given a set, count how many subsets have sum of elements greater than or equal to a given value. Algorithm is simple: solve(set, set_size, val) count = 0 for x = 0 to power(2, set_size) sum = 0 for k = 0 to set_size if kth bit is set in x sum = sum + set[k] if sum >= val count = count + 1 return count For query 2, L=8 and R=12.

They probably wanted to solve the Subset sum problem, finding the “closest” sum of any subset of WORK_AMT values. All submissions for this problem are available. You have been given a set of positive integers.Let the minimum element be LO and sum of all elements in set be HI. Your task is to find out if, for each integer X, ( where X is between LO and HI inclusive ) can a subset of the set be chosen such that the sum of elements in this subset is equal to X. Given an array of integers, find the subset of non-adjacent elements with the maximum sum. Calculate the sum of that subset. For example, given an array we have the following possible subsets: #Problem. The essence of the problem is given a collection of n items of varying size, let T sum be the sum of all item sizes. we need to able to answer the question, does a subset of items exist such that the sum of the items in the sumset is equal to K. where K is some integer that satisfies the constraints K <= T max and (total-K) <= T max. This is similar to the subset sum problem, where you are required to find a subset whom sum is a value k.. Since there is a solution to your problem (you have a subset S whom multiplication is k) if and only if you have a subset of log(x) for each x in the set, whom sum is log(k) (the same subset, with log on each element), the problems are pretty much identical. Count and print all Subarrays with product less than K in O(n) Objective : Given an array of positive integers and integer ‘K’. Write an algorithm to count all the possible sub arrays where product of all the elements in the sub array is less than k. For query 2, L=8 and R=12.

So, the answer to the query is 10 + 13 + 12 + 14 + 14 = 63 mod (\(10^9\) +7) = 63. Such problems allow beginners to try and test their approximate solutions while making sure that the experienced players are tested too. How do we solve this. MIT professor Patrick Winston makes a brilliant note on problem solving at 42:30 in this video. Here is a summary: Definition Does the problem reduce to Knapsack? Subset sum? Something else? Subset sum can also be thought of as a special case of the knapsack problem. One interesting special case of subset sum is the partition problem, in which is half of the sum of all elements in the set (i.e., = (+ ⋯ +) Subset sum problem is an NP complete problem. In a nutshell, NP complete is a set of computational problems for which no efficient solution that will give a reasonably good run time for very large test cases has yet been found. ***Count and print all Subarrays with product less than K in O(n) Objective : Given an array of positive integers and integer ‘K’.
