Multiplication of two polynomials using Linked listGiven two polynomials in the form of linked list. The task is to find the multiplication of both polynomials. Show
Examples: Input: Poly1: 3x^2 + 5x^1 + 6, Poly2: 6x^1 + 8 Output: 18x^3 + 54x^2 + 76x^1 + 48 On multiplying each element of 1st polynomial with elements of 2nd polynomial, we get 18x^3 + 24x^2 + 30x^2 + 40x^1 + 36x^1 + 48 On adding values with same power of x, 18x^3 + 54x^2 + 76x^1 + 48 Input: Poly1: 3x^3 + 6x^1 - 9, Poly2: 9x^3 - 8x^2 + 7x^1 + 2 Output: 27x^6 - 24x^5 + 75x^4 - 123x^3 + 114x^2 - 51x^1 - 18Recommended: Please try your approach on {IDE} first, before moving on to the solution.

Linked List What is Polynomial?A polynomial p(x) is the expression in variable x which is in the form (axn + bxn-1 + …. + jx+ k), where a, b, c …., k fall in the category of real numbers and 'n' is non negative integer, which is called the degree of polynomial. An essential characteristic of the polynomial is that each term in the polynomial expression consists of two parts:
Example: 10x2 + 26x, here 10 and 26 are coefficients and 2, 1 is its exponential value. Points to keep in Mind while working with Polynomials:
How do you add two polynomials to a linked list?Step 1: loop around all values of linked list and follow step 2& 3. Step 2: if the value of a node’s exponent. is greater copy this node to result node and head towards the next node. Step 3: if the values of both node’s exponent is same add the coefficients and then copy the added value with node to the result. How many fields will be in the node for performing polynomial addition?therefore polynomials are the expressions that contain the number of terms with non-zero exponents and coefficients. Consider the following General Represent of Polynomial. here, such as the linked representation of polynomials, each term considered as a node, therefore these node contains three fields. How do you multiply two polynomials using linked list?Given two polynomials in the form of linked list….Approach:
How do you add two polynomials using linked list algorithm?Step 1: loop around all values of linked list and follow step 2& 3. Step 2: if the value of a node’s exponent. is greater copy this node to result node and head towards the next node. Step 3: if the values of both node’s exponent is same add the coefficients and then copy the added value with node to the result. What is the time complexity of multiplying 2 polynomials represented in linked list?Time complexity of the above solution is O(mn). If size of two polynomials same, then time complexity is O(n2). Which linked list is used for multiple variable polynomial?Generalized linked lists When multiplication of two polynomials is possible?When the polynomials are multiplied it is possible they can be monomial, binomial, or trinomial. In order to multiply any two polynomials the steps used are: Multiply the coefficients. Multiply the variables using exponent rules as per the requirement. How do you multiply two polynomials using a linked list?Given two polynomials in the form of linked list….Approach:
Which linked list is used for multiply variable polynomial equation efficiently?Implementation: Polynomials are implemented using single linked lists each node having a coefficient and an exponent part. Pointer is set to to highest coefficient and the lower coefficient are added as link part to one another … the end pointer being set to NULL. How do you represent a polynomial in a linked list?Step 1: loop around all values of linked list and follow step 2& 3. Step 2: if the value of a node’s exponent. is greater copy this node to result node and head towards the next node. Step 3: if the values of both node’s exponent is same add the coefficients and then copy the added value with node to the result.
