Use cf-tool

My config:

clang++ $%full%$ -o $%file%$.out -std=c++17 -Wall -Wshadow -ftrapv -Wno-error -g -fsanitize=undefined

Note than D_GLIBCXX_DEBUG may hide debug info, and -Wextra may be too annoy

.vscode/launch.json 配置：

{
  // clang++ main.cpp -o main.out -std=c++17 -Wall -Wshadow -ftrapv -Wno-error -g -fsanitize=undefined
  // .vscode/launch.json need vscode extension: codelldb and replace 1722 with current contest id
