< p > A < u > list< / u > is an abstract data structure concept that represents an ordered collection of elements, supporting operations such as element access, modification, addition, deletion, and traversal, without requiring users to consider capacity limitations. Lists can be implemented based on linked lists or arrays.< / p >

< li > A linked list inherently serves as a list, supporting operations for adding, deleting, searching, and modifying elements, with the flexibility to dynamically adjust its size.< / li >
< li > Arrays also support these operations, but due to their immutable length, they can be considered as a list with a length limit.< / li >

< p > When implementing lists using arrays, < strong > the immutability of length reduces the practicality of the list< / strong > . This is because predicting the amount of data to be stored in advance is often challenging, making it difficult to choose an appropriate list length. If the length is too small, it may not meet the requirements; if too large, it may waste memory space.< / p >
2024-05-02 01:46:20 +08:00
< p > To solve this problem, we can implement lists using a < u > dynamic array< / u > . It inherits the advantages of arrays and can dynamically expand during program execution.< / p >
2023-12-27 00:48:07 +08:00
< p > In fact, < strong > many programming languages' standard libraries implement lists using dynamic arrays< / strong > , such as Python's < code > list< / code > , Java's < code > ArrayList< / code > , C++'s < code > vector< / code > , and C#'s < code > List< / code > . In the following discussion, we will consider "list" and "dynamic array" as synonymous concepts.< / p >

< p > Many programming languages come with built-in lists, including Java, C++, Python, etc. Their implementations tend to be intricate, featuring carefully considered settings for various parameters, like initial capacity and expansion factors. Readers who are curious can delve into the source code for further learning.< / p >
< p > To enhance our understanding of how lists work, we will attempt to implement a simplified version of a list, focusing on three crucial design aspects:< / p >

< li > < strong > Initial capacity< / strong > : Choose a reasonable initial capacity for the array. In this example, we choose 10 as the initial capacity.< / li >
< li > < strong > Size recording< / strong > : Declare a variable < code > size< / code > to record the current number of elements in the list, updating in real-time with element insertion and deletion. With this variable, we can locate the end of the list and determine whether expansion is needed.< / li >
< li > < strong > Expansion mechanism< / strong > : If the list reaches full capacity upon an element insertion, an expansion process is required. This involves creating a larger array based on the expansion factor, and then transferring all elements from the current array to the new one. In this example, we stipulate that the array size should double with each expansion.< / li >
