hello @PranavM16

ur comparator is wrong.

u need to check if one string is prefix of other or not.
if it is then sort in descending order of length .
otherwise sort in lex order

Ok. I’ll try to change it. But it is also giving compile time error in sort function. Can you help with that? @aman212yadav

Can you also add some comments to explain the if statements and the return statements? I did not understand the logic. Mainly for the return statements @aman212yadav

if one string is prefix of other then string with larger size should come first and then smaller string right?

return a.size() > b.size() ; // is doing the same thing. i,e this line is telling that first string should have bigger lenght compare to second string.
