A counting semaphore was initialized to 10. Then 6P (wait) operations and 4V (signal) operations were completed on this semaphore. The resulting value of the semaphore is
A |
0 |
B |
8 |
C |
10 |
D |
12 |
Let the semaphore be S which is initially 10.
S = 10
Now 6P operations and uv operations were completed on this semaphore.
So final value of S will be
S = 10 - 6 + 4 = 8
