reverse

reverse(v [, start=1 [, stop=length(v) ]] )

Return a copy of v reversed from start to stop.

Examples

In the Julia programming language, the function reverse(s::AbstractString) reverses a string and returns the reversed string.

julia> reverse("Hello, World!")
"!dlroW ,olleH"

Here are some common examples of how the reverse function can be used:

Reverse a simple string:
```
julia> reverse("Julia")
"ailuJ"
```
It reverses the string "Julia" and returns "ailuJ".
Reverse a sentence:
```
julia> reverse("The quick brown fox")
"xof nworb kciuq ehT"
```
The function reverses the sentence "The quick brown fox" and returns "xof nworb kciuq ehT".
Reverse a numeric string:
```
julia> reverse("12345")
"54321"
```
It reverses the numeric string "12345" and returns "54321".

Common mistake example:

julia> reverse(12345)
ERROR: MethodError: no method matching reverse(::Int64)

In this example, the reverse function is called with an argument of type Int64. The reverse function specifically works with strings (AbstractString), so passing an integer results in a MethodError. Make sure to pass a string as an argument to the reverse function.
