Question

Pls help with below homework, I will upvote

Operating systems
The monitor below is an attempt to implement the SSFT algorithm.
monitor disk_scheduler {
condition q; position = busy = 0
move_to(destination) {
if (busy) q.wait(abs(destination - position))
busy = 1
position = destination
release() {
busy = 0
q.signal
1. Explain why the implementation does not correctly enforce the SSTF policy. Construct a scenario
to demonstrate the failure.
