am i the only one facing issues with the test case while i return something random like "abcd" and it gives an error , too many values to unpack

well , isnt this problem about recursive functions ? also why does it work on repl but not here

ive tried my best and i dont see any other way to improve this

and how to do that?

why .title() isnt working?

my code works but it doesnt pass some random tests where everytime it misses the end element, like:
if the array is {ab , bc , cd , de}
it would return {ab , bc , cd , de} (which is indeed the correct answer)
but on some random tests it returns {ab , bc , cd}

ig they do ..... they should be symmetrical as per the question and reversing the second string is the only way i gues
