''' simple solution to day1 (year 2023). first, replace the spelled out numbers with 
their integer counterparts. Then run through each one and add numerical values 
to a list. Concat the first and last values of each list and append them to 
the final list. Lastly, just sum the final list. I didn't separate first and 
second challenge here, so this is number 2. Maybe I will tomorrow. Also, its a 
code challenge, so I don't care about variable names lol.
