SML-problem!

Jo

behold [] = []
    | [x] = [x]
    | [x,x1] = [x1,x2]
    | [x,x1,x2] =
    | [x,x1,x2,x3] =
    | (x::x1::x2::x3::xs) =

så skal du bare explod og implode

| [x,x1,x2] = [x,x1,x2]
    | [x,x1,x2,x3] = if x = #"H" andalso x1 = #"a" andalso x2 = #"n" andalso x3 = #"s" then [#"O",#"t",#"t",#"o"]
    | (x::x1::x2::x3::xs) = if x = #"H" andalso x1 = #"a" andalso x2 = #"n" andalso x3 = #"s" then #"O"::#"t"::#"t"::#"o"]::behold(x2)

gåt udfra at det er det du gerne vil. :o)

#"O"::#"t"::#"t"::#"o"::behold(xs) mener jeg

:-D MANGE MANGE GANGE TAK!!!
