发帖数: 14 | 4 多谢@BabyKnight内推，让我有了这次电面机会。
两道题：
1. 给一个string list, 例如：['a', 'b', 'b', 'c', 'c', 'e', 'e', 'e']，返回出
次次数是中位数的字符。例如本题，应该返回[b, c]。
主要就是两次hash，第一次算每个char的count, 第二次把count作key, char作value即
可。不过有点浪费空间。
2. def crawling()

a = []

题目就是flatten json to a list of map, 有一段json，比如说如下：

"uuid": "abc",
"properties": {
"sessionName": "Test session name",
"waypoints": [
{"uuid": "def", "properties": {"latitude": 3}}
]
}
}
把它转化成List>， map里面uuid是key, properties是value。
所以结果应该像下面

DFL半决赛，靠上周四万年不爆发的Garcon和神经刀CJ2K奠定了优势，周日虽然有时候有些波折，
但是还是有惊无险战胜小薇。
MFL还是老样子，整个队伍萎靡不振，幸好少有的爆发都赶上时候，因为对手更加萎靡，以第七名成

来，就港人的破OL，本来就不行，还老受伤，让我们号兄情何以堪嘛。不说了，明早起来抢WW
周三
早上一起来已经是十二点了，如果有勤奋的同僚，比如之前凌晨四点起床督战的老何，这周就又废
