Given an array of non-negative integers, and a value sum, determine if there is a subset of the given set with sum equal to given sum.
Example 1:
Input:
N = 6
arr[] = {3, 34, 4, 12, 5, 2}
sum = 9
Output: 1
Explanation: Here there exists a subset with
sum = 9, 4+3+2 = 9.
Example 2:
Input:
N = 6
arr[] = {3, 34, 4, 12, 5, 2}
sum = 30
Output: 0
Explanation: There is no subset with sum 30.
Your Task:
You don't need to read input or print anything. Your task is to complete the function isSubsetSum() which takes the array arr[], its size Nand an integer sum as input parameters and returns boolean value true if there exists a subset with given sum and false otherwise.
The driver code itself prints 1, if returned value is true and prints 0 if returned value is false.
Expected Time Complexity: O(sum*N) Expected Auxiliary Space: O(sum*N)
Constraints:
1 <= N <= 100 1<= arr[i] <= 100
1<= sum <= 105
