String sort question approach

#1

Please let me know the approach to this question. Also , can this be done using custom sort function ( using compare ) ?

#2

sort the strings and then according to the first character sort using whose length is bigger.
actually the question is that if two strings have same prefix , then sort according to the length in decreasing order

#3

I think this approach wont work because if there are two strings say " bee " and " bfsuy " . Then normal sorting gives the order - "bee ", "bfsuy " . After that according to your approach , if I consider only the first character and sort on the basis of length , then the order would become - " bfsuy ", "bee " , which is wrong . I think the q. says whenever one string is prefix of other then we should follow the rule of decreasing length. Please clarify this.

#4

try and submit from both the approaches, see when you get the AC.
