Write the following program (you may use C, C++ or Java)
The program creates two
types of threads: Submit & Review
interacting via a common Board.
There are:
9 Submit threads,
9 Review threads and
9 Board Slots.
ê The
Borad:
A board slot has two
fields: S and R.
for i = 1 to 9 {
S[i] = 0
R[i] = 0
}
ê Submit
thread I (1,
...9):
while (true) {
generate
a random number J between 1 and 9
sleep
J
seconds
if (S
[J]
== 0) {
S[J]
= I
display content of
Board
exit
}
}
ê Review
thread I (1, ...9):
while (true) {
generate
a random number J between 1 and 9
sleep
J
seconds
if (S[J] !=0) & (R[J]
== 0) {
S[J]
= I
display content
of Board
if last
thread: display threads statistics ( #trails to find a slot
& time to finish).
exit
}
}
