Q.2)
Given two positive integers n and k, perform a circular shift on the binary representation of n by k positions.
For example, n = 13, k=1, so the result should be 11.

Q.3)
Complete the function allocateMemory() in the below code in C.
int main() {
int *ptr = NULL;
allocateMemory();
*ptr = 5;
printf(“%d”, *ptr);
return 0;
}

Then he asked me about Operating System questions. The questions were: -
a) What is mutex?
b) Difference between mutex and semaphores.
c) How deadlocks occur and how to prevent deadlocks?
d) What is virtual memory and how it is achieved?
e) What is the advantage of using thread over process?

I could not clear this round because the coding section did not go well.
