| 面试前准备：了解编程环境（编译器版本） | ||
|
|
||
| 算法题解： https://github.com/jiangyinzuo/algorithm | ||
|
|
||
| 禁用Github Copilot `:Copilot disable` | ||
|
|
||
| 建立单文件项目 | ||
|
|
||
| -------------------------------- | ||
| 命令行单文件编译运行 ~ | ||
|
|
||
| Java: `java Main.java < 1.in` | ||
| Python: `python3 a.py < 1.in` | ||
|
|
||
| AsyncTask 单文件编译运行 ~ | ||
|
|
||
| `:AsyncTask file-run` | ||
| 标准输入重定向 `:AsyncTask file-run-redir` | ||
|
|
||
| -------------------------------- | ||
| 单步调试 ~ | ||
|
|
||
| Java/Python: 先`:DapToggleBreakpoint`, 再`:DapContinue`，在dap-terminal中输入输出 | ||
|
|
||
| C/Cpp/Rust: `:Termdebug` | ||
|
|
||
| Go Dap ~ | ||
|
|
||
| 调试单文件前，在当前目录`.vscode/launch.json`中添加配置(可以通过`:ReadProjectFile`选择`.vscode/go-debug-single-file.launch.json`) | ||
| >json | ||
| { | ||
| "version": "0.2.0", | ||
| "configurations": [ | ||
| { | ||
| "name": "Launch file", | ||
| "type": "go", | ||
| "request": "launch", | ||
| "mode": "debug", | ||
| "program": "${file}" | ||
| } | ||
| ] | ||
| } | ||
| < | ||
|
|
||
| 然后运行`:GoDebug` (go.nvim封装了nvim-dap, 无需配置) | ||
|
|
||
| Go Dap支持STDIN比较困难 | ||

|
||
| Go Delve ~ | ||
|
|
||
| https://github.com/sebdah/vim-delve | ||
|
|
||
| Go调试单文件，标准输入重定向: `:DlvDebug foo.go -r 1.in` | ||

| for line in stdin.lock().lines() { | ||
| let ll = line.unwrap(); | ||
| let numbers: Vec<&str> = ll.split(" ").collect(); | ||
| let a = numbers[0].trim().parse::<i32>().unwrap_or(0); | ||

| print!("{}\n", a + b); | ||

| Golang的文件名随意，但package name必须是main，这样才能运行`go run foo.go` | ||
| >go | ||
| package main | ||

|
|
