Hi everyone,
I am trying to solve this problem. I found a blog post on the subset sum problem using Python that explains the problem and provides a solution using a recursive approach. I have implemented the solution in Python, and the code is shown below.
def subset_sum(set, n, sum):
if sum == 0:
return True
if n == 0:
return False
if set[n - 1] > sum:
return subset_sum(set, n - 1, sum)
return subset_sum(set, n - 1, sum) or subset_sum(set, n - 1, sum - set[n - 1])
set = [1, 2, 3, 4, 5]
n = len(set)
sum = 10
if subset_sum(set, n, sum):
print("Yes")
else:
print("No")
The code works by recursively checking if there is a subset of the given array whose sum is equal to the target sum. The base cases are when the sum is 0 or the array is empty. In the recursive case, we check two conditions:
- If the last element of the array is greater than the target sum, then we can ignore it and continue with the rest of the array.
- Otherwise, we can either include the last element in the subset or not include it. We do both and check if either of the cases leads to a solution.
The code outputs “Yes” if there is a subset with the desired sum, and “No” otherwise.
I would appreciate it if someone could review my code and let me know if there are any improvements that can be made.
Thanks!
