Medium. Ad: In below code a recursive method is written which tries to add array element into some subset. Hey guys, Today is day 19 of the 100 Days to LinkedIn Challenge. » JavaScript

» DBMS For the last subset will not go for the search because all the remaining numbers must have the sum equals to (.

Time Complexity: O( k!

Don’t forget to hit the follow button✅to receive updates when we post new coding challenges. » Android » Subscribe through email. You have to make K subsets by which all of the subsets have equal sum. Then we will choose any of the value from starting and start our backtracking algorithm according to that and find the subsets with equal sum. » Feedback Fill in your details below or click an icon to log in: You are commenting using your WordPress.com account. Let there is a set of N positive numbers X1, X2, X3, ..., Xn. Here it’s not necessary that the number of elements present in the set is equal. Submitted by Souvik Saha, on February 04, 2020. ( Log Out /  The best stories sent monthly to your email. Experience. (Hacker Rank) ‍. If that sum is not divisible by k. Then we cannot partition into k different elements, so return false. When the answer is true and involves subsets with a low size, this method of placing elements will consider these lower size subsets sooner. » Facebook Please use ide.geeksforgeeks.org, generate link and share the link here. For the first integer the loop will be iterated only once. If the K equals to 1 then it always true and the value of K is greater than N then it is impossible so it is false then. » LinkedIn If you are Preparing for your Interview. » SEO Another speedup is we could sort the array nums, so that we try to place the largest elements first. Even if you are settled down in your job, keeping yourself up-to-date with the latest Interview Problems is essential for your career growth. Attention reader!

We have to find out that can we divide it into two subsets such that the sum of elements in both sets is the same. Change ), You are commenting using your Twitter account.
So, 779 is divisible by 3.

If sum of this subset reaches required sum, we iterate for next part recursively, otherwise we backtrack for different set of elements. » Content Writers of the Month, SUBSCRIBE : The recursive call of the search(…) method in the previous step (Step 1, here) inserts the seconds last integer of the nums array in the groups arrays and recurse itself again.

Our goal reduces to divide array into K parts where sum of each part should be array_sum/K » Internship Partition of a set into K subsets with equal sum. Given an array of integers nums and a positive integer k, find whether it's possible to divide this array into k non-empty subsets whose sums are all equal. » News/Updates, ABOUT SECTION Intuition As even when k = 2 , the problem is a “Subset Sum” problem which is known to be NP-hard, (and because the given input limits are low,) our solution will focus on exhaustive search. Only if cur_sum = sum/k && cur_num >0, we can start another look up process. I was reading up on the set partition problem on this site of Wikipedia: ... they present a DP approach to solving the equal subset sum problem for 2 subsets by finding a subset that sums to half the total sum of the set. » C# » Ajax » Networks After getting the first subset we will go for the other but in that case will not consider the numbers which are already been used for the first subset and those are indicated by the Boolean array. Examples: & ans. Get hold of all the important DSA concepts with the DSA Self Paced Course at a student-friendly price and become industry ready. Visit The Algorists! Space Complexity: O(N), the space used by recursive calls to search in our call stack. Each time when we get a cur_sum = sum/k, we will start from position 0 in nums[] to look up the elements that are not used yet and find another cur_sum = sum/k. You have now reached the end of this article. Explanation: It’s possible to divide it into 4 subsets (5), (1, 4), (2,3), (2,3) with equal sums. Find the sum of all elements of the array. » Java First we need to check some base cases, Good luck with your Programming Interview! We will take a Boolean array to identify the values which are already been used. Please write to us at contribute@geeksforgeeks.org to report any issue with the above content. » DS

To make K no. CS Subjects: And the depth of the search tree is the max number of elements we can put in a group, which is N - k + 1. the time complexity is O(k^(n-k+1)) or O(k^(n-k)). To solve this, we will follow these steps −, Let us see the following implementation to get a better understanding −, Partition Array Into Three Parts With Equal Sum in Python, Print triplets with sum less than or equal to k in C Program, Find the largest area rectangular sub-matrix whose sum is equal to k in C++, Sum of XOR of all possible subsets in C++, Maximum average sum partition of an array in C++, Equal partition of an array of numbers - JavaScript, Partition Array for Maximum Sum in Python, Sum of the products of all possible Subsets in C++, Maximum subset with bitwise OR equal to k in C++, C++ Program to Generate All Possible Subsets with Exactly k Elements in Each Subset, Count all distinct pairs with difference equal to k in C++. A bit more explanation about how we reached at the time complexity: If we do not think about the optimization achieved by the line if (groups[i] == 0) break;then we could think that we are doing O(k) work in for each of the recursive call of search() method. Suppose we have an array of integers called nums and a positive integer k, check whether it's possible to divide this array into k non-empty subsets whose sums are all same.
