My solutions in Rust. Concentrating on writing idiomatic Rust and using efficient algorithms.

Executing

To run a particular puzzle use the --bin parameter to cargo

cargo run --release --bin p1

Benchmarks

To calculate benchmark times run ./benchmark.sh from the top directory. This will build release versions of all puzzles and then execute them collecting timing information.

Times
----------------------------------------
target/release/p1: 27ms
target/release/p2: 7ms
target/release/p3: 111ms
target/release/p4: 19ms
target/release/p5: 734ms
target/release/p6: 153ms
target/release/p7: 8ms
target/release/p8: 7ms
target/release/p9: 566ms
target/release/p10: 21ms
target/release/p11: 1071ms
target/release/p12: 11ms
target/release/p13: 16ms
target/release/p14: 607ms
target/release/p16: 22ms
target/release/p17: 38ms
target/release/p18: 191ms
target/release/p19: 179ms
target/release/p20: 12ms
target/release/p21: 67449ms <- well this is awkward

Total time: 71256ms
