Subset Sum
Detailed guide and Python implementation for the 'Subset Sum' problem.
Problem Statement
Write a function is_subset_sum(arr, total) that returns True if there exists a subset of the non-negative integers in arr that sums to total, and False otherwise.
- •1 <= len(arr) <= 100
- •0 <= arr[i] <= 1000
- •0 <= total <= 10000
Examples
is_subset_sum([3, 34, 4, 12, 5, 2], 9)
True
The subset {4, 5} sums to 9.
is_subset_sum([3, 34, 4, 12, 5, 2], 30)
False
No subset sums to 30.
