number to get a round up.

20. needed.append(num - cnt)

22. needed, counts = list(map(list, zip(*sorted(zip(needed, counts)))))
23.
24. for i in range(len(counts)):

27. remaining -= needed[i]
28. counts[-1] += remaining
29.
30. result = []
31. for cnt in counts:
32. percentage = cnt * 100 / N
33. if percentage - int(percentage) < 0.5:
