Advent of Code 2020

Solutions to all 25 puzzles (with the inputs I was given).

Run program for a specific day (e.g. day 25):

cargo run --release --bin day25

Run and time all solutions:

cargo build --release
/usr/bin/time sh -c 'for d in `seq 1 25`; do echo "----- DAY $d -----"; ./target/release/day$d; echo "----- END DAY $d -----"; done'
