Create a class that can decode the cryptic string below using the following table:
'Hello%20%22World%22%20%2D%201%20is%20%3E0%2E'
# => 'Hello "World" - 1 is > 0.'| Symbol | Code |
|---|---|
| " " (space) | %20 |
| """ (double quote) | %22 |
| "%" (percent) | %25 |
| "-" (hyphen) | %2D |
| "." (period) | %2E |
| "<" (less than) | %3C |
| ">" (greater than) | %3E |
| "" (backslash) | %5C |
| "_" (underscore) | %5F |
Add a method to encode a normal string using all of symbols in the table.
