• Click Run or press Ctrl + Enter
• Output appears in the Output panel
⌨ How input() Works
• Each input() reads one line
• Enter inputs line-by-line in the stdin box
🧪 Problem Mode
• Click Load Starter to get template code
• Write logic only where marked # TODO
🏁 Tests
• Run Samples → visible test cases
• Run All Tests → includes hidden edge cases
• Hidden failures mean logic is incomplete
⚠ Common Mistakes
• Forgot print()
• Extra text like "sum ="
• Infinite loop (timeout)
• Wrong range limits
🏆 XP & Streak
