number of subset sum problem dp code example
Example: subset sum problem using backtracking python
def SubsetSum(set, n, sum) :
# Base Cases
if (sum == 0) :
return True
if (n == 0 and sum != 0) :
return False
# ignore if last element is > sum
if (set[n - 1] > sum) :
return SubsetSum(set, n - 1, sum);
# else,we check the sum
# (1) including the last element
# (2) excluding the last element
return SubsetSum(set, n-1, sum) or SubsetSum(set, n-1, sumset[n-1])
# main

if (SubsetSum(set, n, sum) == True) :
print("Found a subset with given sum")
else :
print("No subset with given sum")
