What is the primary output when splitting a circular linked list into two halves?
- One circular linked list with all elements reversed.
- Two linear linked lists that contain the same elements.
- Two separate circular linked lists of equal length. (correct)
- A single linear list with elements sorted.
In the context of wildcard patterns, what does the '?' character represent?
In the context of wildcard patterns, what does the '?' character represent?
- A placeholder for any single binary digit. (correct)
- A fixed binary digit that cannot be changed.
- An indication of an error in the pattern.
- A marker for the start of the binary string.

Study Notes
Assignment 1 Topics
- The assignment is worth 10 marks and contains 4 parts.
- The assignment requires students to write C programs for four different data structures and algorithms concepts.
- The questions are:
- Implement Radix sort.
- Split a Circular Linked List into two halves.
- Find all binary strings that can be formed from a wildcard pattern.
- Implement Dijkstra's shortest path algorithm using a priority queue.
Radix Sort
- Radix sort is a sorting algorithm that sorts data by digit or character position.
- The assignment requires students to write a C program that implements radix sort.
Circular Linked List
- A circular linked list is a data structure where the last node points back to the first node, creating a loop.
- The assignment requires students to write a C program that splits a circular linked list into two halves.
Wildcard Pattern Binary Strings
- The assignment requires students to find all possible combinations of binary strings that can be formed by replacing the wildcard character ('?') with either '0' or '1' in a given binary pattern.
- For example, for the wildcard pattern "1?11?00?1?", the possible combinations are:
- "1011000010"
- "1011000011"
- "1011000110"
Dijkstra's Algorithm
- Dijkstra's algorithm is a graph traversal algorithm that finds the shortest path between two nodes in a graph.
- The assignment requires students to write a C program that implements Dijkstra's shortest path algorithm using a priority queue.
