python exemple

x = [2, 1.2, 1, 0.5]
max_val = 5

def find_next(state, idx, check=False):
    if(idx == len(x)):
        return print_it(state, check)
    if(sum(state) + x[idx] > max_val):
        find_next(state, idx + 1, True)
    else:
        find_next(state + [x[idx]], idx)
        find_next(state, idx + 1)

def print_it(state, check):
    if check:
        print("")
        print(sum(state),state)
    return


find_next([],0)
