```
#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

end
if left < right
data[left],data[right] = data[right],data[left]
left += 1

end

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

```
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 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:

- Initialize two index variables left and right:

left = 1, right = size - Keep incrementing left index until we see an odd number.
- Keep decrementing right index until we see an even number.
- If left < right then swap data[left] and data[right]

```
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]
