+## [Canonical Path](https://perlweeklychallenge.org/blog/perl-weekly-challenge-112/#TASK1)
+
+> You are given a string path, starting with a slash `/`.
+>
+> Write a script to convert the given absolute path to the simplified
+> canonical path.
+>
+> In a Unix-style file system:
+>
+> * A period `.` refers to the current directory.
+> * A double period `..` refers to the directory up a level.
+> * Multiple consecutive slashes (`//`) are treated as a single slash `/`.
+>
+> The canonical path format:
+>
+> * The path starts with a single slash `/`.
+> * Any two directories are separated by a single slash `/`.
+> * The path does not end with a trailing `/`.
+> * The path only contains the directories on the path from the root
+>   directory to the target file or directory
+

+Input: "/a/b//c/"
+Output: "/a/b/c"
+
+Input: "/a/b/c/../.."
+Output: "/a"

+## [Climb Stairs](https://perlweeklychallenge.org/blog/perl-weekly-challenge-112/#TASK2)
+
+> You are given `$n` steps to climb
+>
+> Write a script to find out the distinct ways to climb to the top.
+> You are allowed to climb either 1 or 2 steps at a time.
+
+### Notes
+This is just finding the `$n + 1` Fibonacci number.
