 UwU finally something **fun**!

 Well! onto part 2...
+
+## part 2
+
+Why the hecc did the 1st part deliberately instruct the programmer
+to count directories multiple times, and the 2nd part went "well,
+actually no, we want a proper size, not an imaginary size"???
+
+thankfully, I have decided to write the parser code separate from
+the summing code, so I could just easily throw the 2nd part out
+while keeping the 1st part.
+
+Anyways! that was probably the most fun chall here yet! Neat™!
