    Optimize the below 1,2,3,4 questions for time:

    1)
    int i;
    if i=0 then i:=1;
    if i=1 then i:=0;

    2)
    int i;
    if i=0 then i:=1;
    if i=1 then i:=0;
    (given that i can take only two values (1,0))

    3)
    int i;
    if i=0 then i:=1;
    else if i=1 then i:=0;
    (given that i can take only two values (1,0))

    4)
    int m,j,i,n;
    for i:=1 to n do
    m:=m+j*n

    5) Expand the following
    a) ISDN
    b) CASE
    c) CSMA/CD
    d) OOPS
    e) MIMD

    6) In the following questions, answer A,B,C,D depending on when
    the errors are detected?
    A if no error is detected
    B if semantic and syntactic checking
    C if during Code genration & Symbol allocation
    D run time

    a) Array overbound
    b) Undeclared identifier
    c) stack underflow
    d) Accessing an illegal memory location

    7) How many page faults will occur for below sequence of pages when LRU
    page replacement algorithm is used ( The memory can only have 3pages):

    1,2,3,4,2,1,5,2,4 (something like that)
