Data Structure --- Binary Tree C Implementation Analysis If we have learned the data structure, we all know the tree. What is the tree?  A tree contains n (n> 0) knots. (1) Each element is called a node. (2) A specific node is called a root node or

Using a single-chain table with leading nodes in C language to simulate the stack structure In the previous two blogs, I used static arrays and dynamic arrays to construct stacks, which is convenient to implement. However, I always feel that
