'''Works with gojq, the Go implementation of jq'''

This entry uses `longest_common_prefix` from [[Longest_common_suffix#jq]] and so the definition is not repeated here.

<lang jq>

# Input: an array of strings

def longest_common_suffix:

def r: explode | reverse | implode;

if length == 0 then "" # by convention

elif length == 1 then .[0] # for speed

else map(r)

| longest_common_prefix

| r

end;</lang>

'''Test Cases'''

<lang jq>def test:

["baabababc","baabc","bbbabc"],

["baabababc","baabc","bbbazc"],

[""],

[],

["Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"],

["throne","cone", "bone"]

| "\(.) => \(longest_common_suffix)";
