因为tuple不能增删改,所以这里不做比较。 因为deque只是和list样子相似,但作用和queue相似,看名字就知道了,所以它只能从两端增删,不能从中间增删,它也就没有insert或者update这样的方法。 pop各种方法有些不一样,另外我们知道pop的时候它会返回被删掉的数据。因此,pop我们会分为pop last、pop(index[list]/key[dict...

Complexity Constant. Iterator validity All iterators, pointers and references referring to elements in both containers remain valid, and are now referring to the same elements they referred to before the call, but in the other container, where they now iterate. ...
For example, if you have the array [[1,2,4],[5,6,7]] and you want to insert the element 3, you can insert 3 into the first array to get [[1,2,3,4],[5,6,7]] and only the element 4 has to be shifted. This often outperforms the more common tree-based data structures ...
