There is a single$-$lane road on a river bridge. Naturally, only traffic in the same direction $($from north to south or from south to north$)$ is allowed on the bridge at any given time. If a vehicle comes from the opposite direction, the vehicles get stuck. At most, $3$ vehicles can be on the bridge at the same time, but all vehicles must be moving in the same direction.

However, if there is heavy two$-$way traffic, allowing continuous passage in one direction would be unfair. Therefore, no more than $10$ consecutive vehicles should be allowed to pass in the same direction. A vehicle approaching the bridge can cross if the bridge traffic is flowing in its direction and the number of consecutive vehicles passing is less than $10.$ Otherwise, it should wait at the bridge entrance. However, if there are no vehicles waiting at the bridge entrance from the opposite direction, more than $10$ consecutive vehicles may pass.

$$ Write software using the PTHREAD library in C language that meets all these requirements and prevents conflicts and congestion.

$$ Plan each vehicle as a separate thread. Automatically generate vehicles moving in random directions within a specified time.

$$ The expected output of the assignment is the running program and showing the working steps on the screen. You can display the output in any format you want.

$$ Numbers represent the number of vehicles. The interface should be updated with each created vehicle.

$$ You need to use Semaphore in the application.

$$ Create an output in the terminal as shown below and continuously update the output for real$-$time updates. For this, create a separate thread and trigger it continuously within a specified time to update the output.
