拆分重复元素集合
给定一个包含重复元素的集合，如何将其拆分成多个不带重复元素的小集合？
例如，对于集合 [29, 36, 37, 37, 39, 39, 955, 955, 955, 961, 961, 962, 962]，可以拆分成三个小集合：
- [29, 36, 37, 39, 955, 961, 962]
- [37, 39, 955, 961, 962]
- [955]
python 实现
以下 python 代码利用元素计数来拆分集合：
datas = [29, 36, 37, 37, 39, 39, 955, 955, 955, 961, 961, 962, 962]
elementcounts = {}
maxcount = 0
for data in datas:
elementcounts[data] = elementcounts.get(data, 0) + 1
maxcount = max(maxcount, elementcounts[data])
sets = [set() for _ in range(maxcount)]
for data, count in elementcounts.items():
for i in range(count):
sets[i].add(data)
print(sets)输出结果：
[set([29, 36, 37, 39, 955, 961, 962]), set([37, 39, 955, 961, 962]), set([955])]
