need to write a python function
need to write a python function that given an input array of integers with 4 entries and a desired
target_sum, returns the number of combinations, of any length, that add up to that target_sum
e.g.:
total_combinations = calculate_combinations([5,
Answer:
It should return 3, as there are 3 combinations of numbers from the input array that add up to 15, namely:
15
5+10
5+10

Did you find the solution? The full answers are bad in the above sense; however, hints are allowed.
You should learn the standard module itertools. The brute-force solution can be based on the itertools.permutations function and on elimination of the same solutions. The standard documentation also shows how to implement it in Python. It can be a good start.
