Longest Common Ending
Write a function that returns the longest common ending between two strings.
Examples
longestCommonEnding("multiplication", "ration") ➞ "ation"
longestCommonEnding("potent", "tent") ➞ "tent"
longestCommonEnding("skyscraper", "carnivore") ➞ ""
Notes
Return an empty string if there exists no common ending.

I have used linear and reverse loop to check & match the characters of Word A with Word B. In liner loop if the sreing is not empty it’ll display the result, else if the sreing is empty then it’ll run a reverse loop and check the charecters again… and then display the result.
with this method i tried these and i got the result as cation
Also if i’m wrong then please let me know…

This seems to work
the solution for potent and tnet should be t rather than empty string…

Not according to @Peter requirement. I think should be empty string. That’s why I was also returning empty string

potent and pot , both words end with t… as well as potent and tnet … so isn’t that the longest common ending then?
