Write a function find triplets that (1) is given a list and a target value and (2) returns a list of three numbers that sum up to the target value. If the triplets don't exist in the list (i.e., no three numbers sum to the target value), return "Not found". You may assume there is only one list of three numbers that sum up to the target value.
