Create all the possible combinations of array a – Software Engineering

The subset-sum drawback is outlined as follows: given a set B of n optimistic integers and an integer Ok, can you discover a subset of B whose parts’ summation is the same as Ok? Design an algorithm to resolve this drawback. Deal with its correctness and operating time.

Enter: set B of n optimistic integers and an integer Ok.

Output: whether or not there exist such a subset of B referred to as B’ its parts summation is the same as Ok.

B’= BA, the place A = during which AB= b1a1 +b2a2 +……+ bnan. The place ai is both zero or 1.

Algorithm:
– For i= 1 to 2n (We’ve got 2n completely different combinations set to be checked)
1. Create all the possible combinations of Array A and do:
– Compute Sum =
– If Sum = Ok then there may be a subset sum to Ok. This subset B’= b1a1, b2a2, ……, bnanwhen ai representing 1.
– return the subset B’
– In any other case return there isn’t any subset sum to Ok.

The run time is O(2n) because it must undergo all possible subsets to seek out the subset that sum to Ok.
