Check if a function output matches its input

I have a function to which I'm passing, one by one) elements of the array as a arguments. Output of a function is a string. How can I check if output of that function is the same as its argument (element of an array). Something like: if string produced by the function is the same as string from the array (function argument) do something else do something. Simplified cod example:

array=(one two three)

for x in ${array[*]}; do
  if [[ -z function $x ]]; then
    echo "${x}"
  fi
done

Thanks.

EDIT: Corrected description (hopefully it makes more sense now).

Sounds like you want

if [[ "$x" == "$(function "$x")" ]]; then ...
