Building a List

    Python oneliners:

    from itertools import combinations
def solve(s):
    return sorted(''.join(x) for r in range(1,1+len(s)) for x in combinations(s,r))

    Or for the fun to use accumulate instead of range(len()):

    from itertools import combinations, accumulate
def solve(s):
    return sorted(''.join(x) for r in accumulate(s) for x in combinations(s,len(r)))
