» Java » Node.js Add to List. » Subscribe through email. Now that all the subsequent recursive call would find at least one integer in each of the index of the groups array.

To make K no. 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. 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. No subscription required! If K is 1, then we already have our answer, complete array is only subset with same sum. » HR Are you a blogger? » CS Basics These tricks are not necessary to solve the problem, but they are presented in the solutions below.

A natural approach is to simulate the k groups (disjoint subsets of nums).

Change ), You are commenting using your Google account. » Python Just me explaining how to solve this Leetcode problem. 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. Add to List. » About us 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.

Interview que. Invariance condition meted. » Contact us By using our site, you 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. Partition of a set into K subsets with equal sum.

Medium. The best stories sent monthly to your email. Writing code in comment? Solved programs: » C# Web Technologies: Firstly, we know that each of the k group-sums must be equal to target = sum(nums) / k. (If this quantity is not an integer, the task is impossible.) A compilation of 100 Java(Interview) Programming problems which have been solved. » Embedded Systems

Given an integer array of N elements, the task is to divide this array into K non-empty subsets such that the sum of elements in every subset is same. Change ), You are commenting using your Facebook account. If the target sum cannot be achieved, or if you can only reach to the target with an index that has already been visited. And since we are calling the search() method recursively for each of the N integers in the nums array, this gives us the time complexity of. » Web programming/HTML ❤ We can feature your method in one of the blog posts. If N < K, then it is not possible to divide array into subsets with equal sum, because we can’t divide the array into more than N parts. Thank you for reading it.

I got a very interesting problem today which I thought would be great sharing. Interview coding problems/challenges, Partition a set into k subset with equal sum: Here, we are going to learn to make partitions for k subsets each of them having equal sum using backtracking.

to ace technical interviews. Do you think you really know about Fibonacci Numbers? 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. In below code a recursive method is written which tries to add array element into some subset. Featured on Meta Hot Meta Posts: Allow for removal … The above steps would be true unless the groups array of length k has at least one integer in all of its indices, i.e, for the last k integers of the integer array nums. Computing the time complexity of the recursive algorithm was real fun. For each recursion, check if the current target sum can be achieved , if it can be then return true. For the first integer the loop will be iterated only once. » Content Writers of the Month, SUBSCRIBE If you come across any of these questions in your interview. We will sum up all the values and divide the Sum by K. Please write to us at contribute@geeksforgeeks.org to report any issue with the above content. » DBMS This is a standard interview problem to make partitions for k subsets each of them having equal sum using backtracking. Partition of a set into K subsets with equal sum. » Machine learning

» Kotlin » O.S. Please write comments if you find anything incorrect, or you want to share more information about the topic discussed above. You have to make K subsets by which all of the subsets have equal sum. I want to do this with a set of values not more than 10 integers, with values not bigger than 10 , and less than 5 subsets.
