Explanation of Solution
Linked list:
Linked list is a linear and dynamic data structure which is used to organize data; it contains sequence of elements which are connected together in memory to form a chain. The every element of linked list is called as a node.
List head:
List head is a pointer used to point the first node in the linked list and it is also called as “head pointer”; if the “head pointer” points to a “NULL” value, then it is considered that the “list is empty”.
Graphical representation of linked list:
The graphical representation of a linked list is as follows:
Function to print the value stored in the first node of a list:
//Definition of printing the first node function
void printFirst(ListNode *ptr)
{
/*Check the list w...

- Write a function that returns the greatest common divisor (GCD) of integers in a list. Use the following function header:def gcd(numbers):Write a test program that prompts the user to enter five numbers, invokes the function to find the GCD of these numbers, and displays the GCD.arrow_forwardExercise, maxCylinderVolume F# system function such as min or methods in the list module such as List.map are not allowed Write a function maxCylinderVolume that takes a list of floating-point tuples that represent dimensions of a cylinder and returns the volume of the cylinder that has the largest volume. Each tuple has two floating point values that are both greater than zero. The first value is the radius r and the second value is the height h. The volume of the cylinder is computed using ??2h. The value π is represented in F# with System.Math.PI. If the list is empty, return 0.0. Examples: > maxCylinderVolume [(2.1, 3.4); (4.7, 2.8); (0.9, 6.1); (3.2, 5.4)];;val it : float = 194.3137888> maxCylinderVolume [(0.33, 0.66)];;val it : float = 0.2257988304arrow_forwardWrite a function list2DigitOdd() that creates and returns a list that contain all positive 2-digit odd numbers. The function call list2DigitOdd() will return a list containing 11, 13, 15, ..., 99.arrow_forward
- OCaml Code: Attached are the instructions. Make sure to read the instructions carefully and write your own test cases to make sure the code works. Make sure to include a screenshot of the correct code with the test cases that is used along with the output of the code being passed.arrow_forwardQ1:Write a function that returns a new list by eliminating theduplicate values in the list. Use the following function header:def eliminateDuplicates(lst):Write a test program that reads in a list of integers, invokes the function,and displays the result. Here is the sample run of the program Enter ten numbers: 2 3 2 1 6 3 4 5 2The distinct numbers are: 1 2 3 6 4 5 Q2:Write a program that reads in your Q1 Pythonsource code file and counts the occurrence of each keyword in the file.Your program should prompt the user to enter the Python source code filename. This is the Q1: code: def eliminateDuplictes(lst):newlist = [] search = set() for i in lst: if i not in search: newlist.append(i) search.add(i) return newlist a=[] n= int(input("Enter the Size of the list:")) for x in range(n):item=input("\nEnter element " + str(x+1) + ":") a.append(item) result = eliminateDuplictes(a) print('\nThe distinct numbers are: ',"%s" % (' '.join(result)))arrow_forwardJS Write a function named list_concat that has a single parameter. This parameter will be a list/array. The parameter's entries will be strings. Your function needs to return a string. The returned string's value should be the concatention of all of the entries in the parameter with a space after each entry. Sample test cases: list_concat(["single"]) evaluates to "single list_concat(["limit", "break", "ready"]) evaluates to "limit break readyarrow_forward
