Shortest Job Next (SJN) scheduling algorithm may lead to starvation.

Explanation:
The Shortest Job Next (SJN) scheduling algorithm selects the process with the smallest total execution time to execute next. It is also known as the Shortest Job First (SJF) scheduling algorithm.

In the SJN algorithm, the process with the shortest burst time is given the highest priority. This means that if there are multiple processes with shorter burst times than the currently running process, they will be executed first. This scheduling algorithm aims to minimize the average waiting time of processes.

However, the SJN algorithm may lead to starvation for longer processes. This is because if a long process arrives first, it will have to wait for all the shorter processes to complete before it gets a chance to execute. If there are continuous arrivals of shorter processes, the long process may never get a chance to execute, resulting in starvation.

Example:
Let's consider an example to illustrate this scenario:

Process 1: Burst time = 10
Process 2: Burst time = 5
Process 3: Burst time = 2

In the SJN algorithm, Process 3 will be executed first as it has the shortest burst time. After Process 3 completes, Process 2 will be executed, and finally, Process 1 will be executed.

Now, let's assume that there is a continuous arrival of processes with burst times shorter than Process 1. In this case, Process 1 will keep waiting for all the shorter processes to complete, resulting in starvation. It will never get a chance to execute as it has the longest burst time.

Therefore, the SJN scheduling algorithm may lead to starvation for longer processes, making it an inappropriate choice in certain scenarios.
