# Template for reading all lines from stdin and printing the line count to stdout. # Copy this code to your IDE to get started. lines = [] while True: try: lines.append(input()) except EOFError: break print(len(lines))
Rules

• You're welcome to participate alone or in a team.
• You may submit multiple solutions and explore different programming languages.
• Stick to the standard library of your language, no further dependencies/libraries, except the ones which OneCompiler provides (e.g. NumPy for Python).
• Ensure your code aligns to the template (Python, Rust, Go, Kotlin, JavaScript, C#, TypeScript, C++, Java, C, Swift, Scala, Ruby), reading the puzzle input from stdin (terminated with end-of-file), and printing the solution to stdout.
• Please refrain from making network requests, reading data from files, or storing data in variable/function/class names for reflection.
