# 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...
