Write a program to implement round robin scheduling concept using a linked list. Each node will represent a process with attributes as <PID, CPU_time>. A quantum time T will be input by the user.

A process will be executed (when user wants) for quantum time T and the CPU_time will be updated with CPU_time T, and the current process node is deleted from the beginning and added to the end of the list. If the updated CPU_time is <=0, then the process is deleted from the list.

After a process is executed for T time, the the next process in the queue is executed upon user choice. The entire process gets completed when all process nodes are deleted.

Wedding Game

In a wedding that you are attending, there are some chairs that have digits inscribed at their backs. The chairs are lined in a row such that they form a string of the digits. Find the minimum number of sets M that can be formed from these digits such that:

1. The number of digits in each set is one or more than one. 2. Each set is formed using consecutive digits and no digit can be used more

than once.

3. In each set, the number formed using the digits is less than or equal to Y.

Input Specification:

input1: S, string of digits

input2: Y. No number should be greater than Y

input3: Size of the String S

Output Specification:

Your function should return M, the minimum number of sets
