The idea of big data processing is generally like this: Divide a file that cannot fit in the memory into small files according to a certain method, and then see if there is a suitable data struct
Category: Data Structure
Data structure is the way a computer stores and organizes data. Data structure refers to a collection of data elements that have one or more specific relationships with each other. Under normal circumstances, a carefully selected data structure can bring higher operating or storage efficiency. Data structure is often related to efficient retrieval algorithms and indexing techniques.
[Data Structure] During the secondary line of the binary tree, a iterator is realized to traverse the binary tree.
1. Create a node of the binary tree
