CSC PAPER ON 5th AUGUST AT VIJAYAWADA
Hi,friends this is trinadh ,student of vrsec, cse branch. i want to share my
expeience with us, friends this is my 7th attempt, CSC conducted campus
selection in aug5th in my college,they are around 300 students are
participated in this selection ,they conducted2 written tests one
appititude,anothere one is techincal test ,after this they short the list 75
members,for these members they conducted JUST A MIN,and ESSAY WRITING ,after
this 2 rounds they shorted 30 members ,again they conduct techinacal , HR
round , in tech mainly they concentrate on DBMS, SO prepare this
throughly.finally they selected 21 members, i m one of these members. thanks
god.
Friends dont be loose hope and confidence ,god wil help u , friends for
techinal test the questions which are mentioned in previous papers is more
enough, so u must go through once,

value or emptylist if it is the last node.
b)a more sophisticated kind of linked list is a double linkedlist or two way
linkedlist .Each node has two links ,one to the previous node and one to the
next node.
c) in a circleLinkedList ,the first and last nodes are linked together.this
can be done only for double linked list.
d) to traverse a circular linkedlist ,u begin at any node and follow the
list in either direction until u return to the original node.

not used to store the data
a) true
b) false
friends for technical test these questions are enough, but apptitude test
some what tough,for this u must go through RS AGRWAL , this is enough to
qualify these 2 tests
ALL THE BEST ,dont be loose hope and courage ,
