# makefile  [PROVIDED]
# Course toolchain: GCC 15.2, C++26.
# Three build modes:
#   make            -> debug (default): -g -O0, no sanitizers
#   make debug      -> same as default
#   make sanitize   -> debug + AddressSanitizer/UndefinedBehaviorSanitizer
#   make release    -> optimized: -O2 -DNDEBUG, no sanitizers
#   make clean      -> remove objects and the binary
#
# The autograder uses the sanitizer build, run `make sanitize` before submitting.
