## Reversed String
|
||||
|
||||
Write a function called ```revstring``` that takes a string as input and returns the reversed string.
|
||||
|
||||
### Function Signature:
|
||||
```python
|
||||
def revstring(x).
|
||||
# return your solution
|
||||
```
|
||||
|
||||
#### Requirements
|
||||
- The function should return the input string reversed
|
||||
- Your function will be tested with various cases, including:
|
||||
- An empty string
|
||||
- A single character
|
||||
- A palindrome ("racecar")
|
||||
- A string of numbers ("12345")
|
||||
- Special characters
|
||||
- A normal string ( "Hello World" )
|
||||
|
||||
#### Example:
|
||||
```python
|
||||
revstring("Hello World") # returns "dlroW olleH"
|
||||
revstring("") # returns ""
|
||||
revstring("racecar") # returns "racecar"
|
||||
revstring("12345") # returns "54321"
|
||||
revstring("!@# $%") # returns "%$ #@!"
|
||||
```
|
||||
You can copy this into your problems solution
