something like ```listOf("a", "b", "c", "c").fold(mutableListOf<String>()) { acc , s -> ...

something like

listOf("a", "b", "c", "c").fold(mutableListOf<String>()) { acc , s ->
        if (s != acc.lastOrNull()) {
            acc.add(s)
        }
        acc
    }

maybe?
Ah no it's not going to work, it will just remove all consecutive characters except the first one

[ghedeon]

why not? Is the definition of adjacent distinction different from this?

[Dias]

well it depends on what Ben wanted

[Dias]

my code would reduce "a", "b", "c", "c", "c", "c" to "a", "b", "c", but maybe he wanted it to be "a", "b", "c", "c"

[Dias]

basically reduce by pairs of adjacents
