# Run tests
task run-v -- 0042-trapping-rain-water

# Benchmark
task bench -- 0042-trapping-rain-water

# Format code

Adding a new problem

task new -- 9-palindrome-number scaffolds both files with the correct package name and LeetCode URL (auto-pads to 0009-palindrome-number). Just write the function signature and tests.
