hello piyush,
store all valid strings in vector and then sort them lexicographically and then print

#3

Its not working…not printing anything,written comp in sort also still same.

But whats wrong with the first approach

#4

@piyush.bansal8158625
you were not getting output because u passed vector v by value but actually u shoud pass it as reference.
I have made some change in ur code pls check.

ur code is also correct just pass vector v by reference

@piyush.bansal8158625
see for bottom view ,ur logic need bit modifications. in ur map strore height and level for each key.
update ur map in only two cases
a) case 1 -> when key is encountered first time
b) case 2-> when new level value is more than then stored level value for a given key

pls check ur thread , i have shared one example where ur code is failing

for k nodes , i think someone else is taking it. and i cannot intervene .
