Other data structures would also be able to accommodate similar data. In Python, a similar object with better language support would be a list of lists.nested_list = [[0, 1], [2, 3]] However, a list of lists cannot always represent the merging of two datatrees with different ...

Today we're implementing a least recently used cache with priorities and expiry, using only the Python standard library. This is a bIG TEch CoDINg InTerVIEW problem, so we'll work hard to stay away from the correct™ data structures, but we'll end up w
classification trees, each with slightly different data. When we get a new x and want to predict hatwidey, we ask each tree to make its prediction, then pick the most common answer as our prediction. What do I mean by “slightly different data”? To be specific, a random forest is bu...
