Regarding use of STL

#1

In which types of questions can we use STL? Can we use STL in this question instead of creating our own list data structure??

#2

@ranahiten8 you should practice by implementing your own data structures in the beginning. STL is good for contests for saving time and when you are already proficient and confident with the data structures. But in the beginning, you should try to implement yourself.

#3

Can we use STL in interviews??

#4

@ranahiten8 depends on the question. In some questions you can, some questions require you to implement your own.
