@anjaligoswami That's really not required as per the guidelines. So adding such PR would higher the risk of getting excluded from the event. In case you are searching for some good-first-issue you should continue with the space and time complexity section, that we discussed over Issue #77 . As per your knowledge base, It's easy for you to handle :)
