# Solving the Subset Sum Problem using Dynamic Programming in Java

Solving the Subset Sum Problem using Dynamic Programming in Java. How to solve Subset Sum Problem using Dynamic Programming in Java. We can use dynamic programming to save time and get best performance.

Subset sum problem is a common interview question asked during technical interviews for the position of a software developer.

It is also a very good question to understand the concept of dynamic programming.### ubset Sum Problem Statement

The problem statement is as follows :

`Given a set of positive integers, and a value sum S, find out if there exists a subset in the array whose sum is equal to given sum S`

An array B is the subset of array A if all the elements of B are present in A. Size of the subset has to be less than or equal to the parent array.

Let’s take an example :

`A = { 3, 2, 7, 1}, Sum = 6`

`Output: True`

In this case the subarray {3, 2, 1} gives the sum 6. Hence we output true.

## Max Heap Data Structure Implementation in Java - JournalDev

In this tutorial, we will cover everything you need to know to implement max heaps in java from scratch. A max heap is a complete binary tree in which the value of a node is greater than or equal to the values of its children. Max Heap data structure is useful for sorting data using heap sort.
