Preface: Originally decided to learn data structure to learn things, the result has been Gu until now.. Line tree is a kind of advanced data structure. It is a kind of binary tree, that is to say, for a line segment, we will use a binary tree to represent it. Text: Line tree can do single point query, single point modification, interval query, ...
