I am new to Julia why the function is returning value 4:4 what does it means ??

```plaintext
findnext("o", "xylophone", 1)

It means that the first occurrence of query string `"o"` after index 1 in `"xylophone"` occurs at indexes `4:4` - that is, the indices from 4 up to and including 4:

```julia
julia> "xylophone"[4:4]
"o"

```

also note

```julia
julia> findnext('o', "xylophone", 1)
4

```

This is not a bug — it’s an intentional difference between strings and characters
