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.
