CP Templates Pro 🚀

Fast boilerplate templates, custom template vault, and instant keyboard shortcuts for Competitive Programming (Codeforces, LeetCode, CodeChef, AtCoder, CSES).

Are you tired of copy-pasting your competitive programming boilerplates, setting up fast I/O, writing ios_base::sync_with_stdio(false), and typing while(t--) in every contest?

CP Templates Pro solves this once and for all. With one keyboard shortcut, insert your favorite competitive programming template, switch between algorithms (DSU, Segment Tree, PBDS), or create and manage your own custom templates directly inside VS Code!

🚀 Quick Start

1. Open or create any code file in VS Code (e.g. solution.cpp).
2. Press Ctrl+Alt+I (Mac: Cmd+Alt+I) to instantly insert your default fast I/O multi-test template:

   #include <bits/stdc++.h>
   using namespace std;
   
   int main()
   {
       ios_base::sync_with_stdio(false);
       cin.tie(nullptr);
       cout.tie(nullptr);
       int t;
       cin >> t;
       while (t--)
       {
           // code here
       }
       return 0;
   }
   

3. Or press Ctrl+Alt+T (Mac: Cmd+Alt+T) to choose from the list of templates.

🛠️ How to Create Your Own Custom Template

2. Press Ctrl+Alt+N (or open Command Palette Ctrl+Shift+P and type CP: Create New Custom Template).
3. Select whether to use selected code, the entire file, or start blank.
4. Give your template a name and choose the language.
5. Your template is now permanently saved! You can insert it anytime via Ctrl+Alt+T or set it as your default template.
