Task 1: "Canonical Path
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
Example
Input: "/a/"
Output: "/a"
Input: "/a/b//c/"
Output: "/a/b/c"
Input: "/a/b/c/../.."
Output: "/a"
"
My notes: ok, I like this. Pretty straightforward, but a nice practical problem.
Task 2: "Climb Stairs
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.
Example
Input: $n = 3
Output: 3
Option 1: 1 step + 1 step + 1 step
Option 2: 1 step + 2 steps
Option 3: 2 steps + 1 step
Input: $n = 4
Output: 5
Option 1: 1 step + 1 step + 1 step + 1 step
Option 2: 1 step + 1 step + 2 steps
Option 3: 2 steps + 1 step + 1 step
Option 4: 1 step + 2 steps + 1 step
Option 5: 2 steps + 2 steps
"
My notes: looks pretty straightforward, although may not generate the options
in the same order.
