@Utsav1998 Using Java 8 Stream may NOT be faster than a "for loop" but the Stream is more "fluent" in terms of Functional Programming, and the complexity of that stream is indeed O(x).
@Singhalr31 For a simple "for" loop (without Collections or Maps), Java 8 Stream "could be" overkill. If you need to iterate over a "LARGE" Collection (or Map) , however, Java 8 may be faster because you could avoid creating LOTS of "intermediate" Objects by simply streaming data in the Collection from one operation to another.

then why the hell we are getting time error when using for loop but not when using streams :(
