 I am hoping this year to find solutions that will run in a reasonable amount of
 time on a Raspberry Pi 4 Model B with 4 Gigabytes of RAM and a Cortex A72
-processor. The Pi-4 is roughly 500-600 times faster than the first computer I
-purchased in the late 90s (200 MHz Pentium MMX with 64 Megabytes
-of RAM). Below I have the time it takes for the problem to finish on the third
-run of my solution after compilation on my Raspberry Pi.
