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.
