Delete Consecutively Repeated String

Question

I have the following text:

text = {"hello","hello","hello","c","a","e","e","hello","hello"}

Now I would like to do the following:

Delete every string that is "hello" and repeats itself consecutively.

Result:

text = {"hello","c","a","e","e","hello"}

Answer 1

For version 11.3:

SequenceReplace[text, {"hello" ..} -> "hello"]

One approach for the versions older than 11.3:

Split[text] /. {"hello" ..} -> "hello" // Flatten

Answer 2

Also

ReplaceRepeated[text, {a___, Longest["hello" ..], b___} :> {a, "hello", b}]

{"hello", "c", "a", "e", "e", "hello"}

Answer 3

Since V 13.1 there is DeleteAdjacentDuplicates:

DeleteAdjacentDuplicates[text, ## == "hello" &]

{"hello", "c", "a", "e", "e", "hello"}
