Go language data structure analysis: master the secrets of queues and stacks

Go 语言数据结构精解:掌握队列和栈的奥秘

前言

栈和队列是计算机科学中至关重要的数据结构,在各种应用中发挥着不可或缺的作用。在 Go 语言中,它们提供了强大的工具来管理数据并解决复杂的问题。本文将深入探讨 Go 语言中的栈和队列,提供清晰的解释、代码示例和实战案例,让你对这些数据结构有深入的理解。

队列

队列是一种遵循先入先出 (FIFO) 原则的线性数据结构。它的操作包括:

  • Enqueue():将一个元素添加到队列的末尾
  • Dequeue():从队列的开头移除一个元素
  • Peek():读取队列中第一个而不删除元素

代码示例:

type Queue []int

func (q *Queue) Enqueue(x int) {
    *q = append(*q, x)
}

func (q *Queue) Dequeue() int {
    if q.IsEmpty() {
        panic("queue is empty")
    }
    x := (*q)[0]
    *q = (*q)[1:]
    return x
}

func (q *Queue) Peek() int {
    if q.IsEmpty() {
        panic("queue is empty")
    }
    return (*q)[0]
}

func (q *Queue) IsEmpty() bool {
    return len(*q) == 0
}

实战案例:

  • 任务队列:将任务添加到队列中,然后按照先到先服务的顺序处理它们。

栈是一种遵循后入先出 (LIFO) 原则的线性数据结构。它的操作包括:

  • Push():将一个元素压入栈的顶部
  • Pop():从栈的顶部弹出并移除一个元素
  • Peek():读取栈顶元素而不删除元素

代码示例:

type Stack []int

func (s *Stack) Push(x int) {
    *s = append(*s, x)
}

func (s *Stack) Pop() int {
    if s.IsEmpty() {
        panic("stack is empty")
    }
    x := (*s)[len(*s)-1]
    *s = (*s)[:len(*s)-1]
    return x
}

func (s *Stack) Peek() int {
    if s.IsEmpty() {
        panic("stack is empty")
    }
    return (*s)[len(*s)-1]
}

func (s *Stack) IsEmpty() bool {
    return len(*s) == 0
}

实战案例:

  • 函数调用:栈用于存储函数调用时的局部变量和上下文。
  • 递归:栈用于存储递归函数调用的返回地址。
  • 括号匹配:利用栈来检查括号是否匹配。

How to use the 'strings' package to manipulate strings in Go step by stepHow to use the 'strings' package to manipulate strings in Go step by stepMay 13, 2025 am 12:12 AM

Go's strings package provides a variety of string manipulation functions. 1) Use strings.Contains to check substrings. 2) Use strings.Split to split the string into substring slices. 3) Merge strings through strings.Join. 4) Use strings.TrimSpace or strings.Trim to remove blanks or specified characters at the beginning and end of a string. 5) Replace all specified substrings with strings.ReplaceAll. 6) Use strings.HasPrefix or strings.HasSuffix to check the prefix or suffix of the string.

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
