Punctuation Run Collapse

Problem

Collapse runs of the same punctuation character into a single character, for example "!!" becomes "!".

Given text, return the collapsed text.

Hint

Skip a character when it repeats the previous punctuation character.

case 1

in: ["Wow!!!"]

expected: "Wow!"

case 2

in: ["a...b"]

expected: "a.b"

case 3

in: ["no punctuation"]

expected: "no punctuation"
