```julia
#this method sort the array that all
#the even number in the first and the odd
#number in the even, and reutnr #the number os swap,
#e.g. in array = [17,4,8], there is a 17 odd number and 8 #even number. swaping so swapping them and the move is 1
function sort_even_odd(data)
left = 1
right = length(data)
moves = 0
while left < right
while iseven(data[left]) && left < right
left += 1
end
while isodd(data[right]) && left < right
right -= 1
end
if left < right
data[left],data[right] = data[right],data[left]
left += 1
right -= 1
moves += 1
end
end
#data, moves
moves
end
data = [17 4 8];
println("Total " , sort_even_odd(data))
```

FYI, it looks like you’re using quoting intended for speech rather than code. You want to use 3 backticks at the top and bottom of code blocks or press the button that looks like ``. Compare
> function foo(speech)
> println(“this doesn’t look good”)
> end
to
```julia
function bar(code)
println("ahh, much better")
end
```
You can still edit your post to fix it.
You should probably also say more about what your specific problem is, what else you’ve tried, etc. [See this post](https://discourse.julialang.org/t/psa-make-it-easier-to-help-you/14757) for more information on how to write a question in a way that helps others to help you.

Without using fancy stuff, here is a simple implementation of the algorithm:
1. Initialize two index variables left and right:
left = 1, right = size
2. Keep incrementing left index until we see an odd number.
3. Keep decrementing right index until we see an even number.
4. If left \< right then swap data[left] and data[right]
```julia
function sort_even_odd(data)
left = 1
right = length(data)
moves = 0
while left < right
while iseven(data[left]) && left < right
left += 1
end
while isodd(data[right]) && left < right
right -= 1
end
if left < right
data[left],data[right] = data[right],data[left]
left += 1
right -= 1
moves += 1
end
end
data, moves
end
julia> data = [17 4 8];
julia> sort_even_odd(data)
([8 4 17], 1)
```

thanks dear,
its working perfect.
i did not know that i can making the swap like this → data[left],data[right] = data[right],data[left]
