+
+# part 1
+
+UwU finally something **fun**!
+
+Writing the recursive bits weren't that hard; Debugging them
+to figure out why aren't they working is another thing. I spent
+a solid hour trying to debug my code completing correctly on
+the sample test data, and not on my chall; The total size was
+somehow *way* too small. It turned out that I've had an invalid
+string replace in handling the `..` case in the recurse function. 
+As long as a branch never further branched out (so, one directory
+continued through a path of more directories containing one or
+zero directories), it was all fine. Otherwise, pwd was set to
+two slashes, which broke Things.
+
+i hate how I handled half of the code as a subshell, but I don't
+care enough about it to rewrite it now
+
+Well! onto part 2...
