CP Debug Printer

Auto-generate cerr debug print statements for C++ competitive programming variables.

Usage

1. Click on any variable name in your C++ file
2. Press Ctrl+Shift+D
3. Debug print is inserted on the next line automatically

Supported Types

• int, long long, string → cerr << "n: " << n << "\n";
• vector<int> → iterates and prints all elements
• vector<vector<int>> → prints 2D grid row by row
• map<int,int> → prints key->value pairs
• set<int> → prints all elements
• stack<int> → prints all elements
• queue<int> → prints all elements
• pair<int,int> → prints {first, second}

Why?

In competitive programming, cerr prints to stderr which the judge ignores — so you can leave debug lines in your code and submit safely.
