i need to write a function for two strings, and , that may or may not be of the same length, determine the minimum number of character deletions required to make and anagrams. Any characters can be deleted from either of the strings.  
For example, if and , we can delete from string and from string so that both remaining strings are and which are anagrams.  
for example = a = cde , b = abc ; we delete from a → de and from b → ab so we return 4.

```nohighlight

function makeAnagram(a::String,b::String) 

  count = 0
  map = Dict{String, Int}()
  for value in a
     if !haskey(map, value)
       map[value]=1
      continue
     end
  end
   for value in b
     if !haskey(map, value)
       count+=1
      continue
     end
     if haskey(map, value)
       map[value]-=1
      continue
     end
  end
     while haskey(map, value)
           count+=1
     end
return count 
end

a = ["a" , "b", "c"]
b = ["q"]
println("Total " , makeAnagram(a, b))

```

Well, if I paste your code into the repl I get a different error:

```julia
julia> println("Total " , makeAnagram(a, b))
ERROR: MethodError: Cannot `convert` an object of type Char to an object of type String
Closest candidates are:

```

On which operating system do you work?  
Does your Repl work at all?  
Try:

```julia
julia> 1+1
2

julia> sin(pi)

julia> versioninfo()

What is your output of “versioninfo()”?

Well, this is not the output of the function versioninfo().

Sorry, but I have the impression that you want someone else do your homework for you and that you not even sit at a computer that has Julia installed. ☹

Dear, I just learn this language and what I asked is to look on the code that I write and check if the logic is fine. What I mean is

1. if the definition of string in the func is write.
2. The if like that definition an array of string.  
a = [“a” ,“b”]

That what I need  
Thank

Well, I am sorry, but I cannot help you if you do not have access to a computer where Julia is installed. If you only have access to a web-browser you could try Julia box:

Your function makeAnagram has two strings, a and b, as input paramters.  
You try to call it with two arrays of (single letter) strings. As there is not function defined which expects two arrays of strings you are lost.  
Try

```julia
function makeAnagram(a::Array,b::Array)

```

Later on in your function body this part

```julia
while haskey(map, value)
       count+=1
end

```

will throw a Undefined error, because `value` is not defined.
