Advent of Code 2015 in C

See https://adventofcode.com/2015/ for puzzle texts and inputs.

Execute run.sh to run all solutions for all days (using bash + awk). Needs a C compiler toolchain like gcc or Clang.

Inputs are read from a input.txt file in the respective directory for each day's solution.

for d in */; do cd $d && cc -Ofast -march=native main.c -lcrypto && ./a.out && echo "" && cd ..; done
(for d in */; do cd $d && cc -Ofast -march=native main.c -lcrypto && ./a.out && cd ..; done) | awk 'BEGIN {sum=0.0} NR%4==0 { gsub(/ms$/,"", $2); sum += $2; } END { printf "Total time: %.2fms\n", sum }'
