Concept: Adding Two Polynomials Using Linked List
Introduction: Adding two polynomials using a linked list involves representing each polynomial as a linked list where each node contains the coefficient and exponent of a term. This approach allows efficient manipulation and addition of polynomials.
Steps to Add Two Polynomials:
- Represent each polynomial as a linked list where each node contains two fields: coefficient and exponent.
- Traverse both linked lists simultaneously, comparing the exponents of the current nodes.
- If the exponents are equal, add the coefficients and create a new node with the sum and the common exponent.
- If one exponent is greater, copy the term with the larger exponent to the result and move to the next node in that list.
- Continue until all terms from both polynomials are processed.
- Attach any remaining terms from either polynomial to the result.
Key Observations:
- Efficiently handles sparse polynomials by skipping zero coefficients.
- Maintains the order of terms based on descending exponents.
- Uses dynamic memory allocation, making it flexible for polynomials of varying sizes.
Advantages:
- Dynamic memory usage ensures efficient handling of large polynomials.
- Easy to implement and extend for other polynomial operations like subtraction or multiplication.
Disadvantages:
- Overhead of dynamic memory allocation and pointer management.
- Requires careful handling to avoid memory leaks.
Time Complexity:
- O(max(m, n)), where m and n are the number of terms in the two polynomials.
