Stack: a special linear table that allows insertion and deletion of elements only at a fixed end. One end for data insertion and deletion is called the top of the stack, and the other end is called the bottom of the stack. The data elements in the stack follow the principle of Last In First Out LIFO (Last In First Out ...

Chapter 2 sparse arrays and queues
2.1 sparse array
2.1.1 basic introduction
When most elements in an array are 0 or the same value array, sparse array can be used to save the array (compress redundant data)
Representation of sparse array:
How many rows and columns are there in the first row? How many different values are there (relati ...
