Types of Linked List
A sequence of data elements connected through links is called a linked list (LL). The elements of a linked list are nodes containing data and a reference to the next node in the list. In a linked list, the elements are stored in a non-contiguous manner and the linear order in maintained by means of a pointer associated with each node in the list which is used to point to the subsequent node in the list.
Linked List
When a set of items is organized sequentially, it is termed as list. Linked list is a list whose order is given by links from one item to the next. It contains a link to the structure containing the next item so we can say that it is a completely different way to represent a list. In linked list, each structure of the list is known as node and it consists of two fields (one for containing the item and other one is for containing the next item address).

- 3. lookup_friends_heights This function takes a friends database (a list of dictionaries, like the previous functions) and a list of friends names, and it returns a list of heights for the specified friends. If a given friend's name is not present in the friends database, we put a None in the corresponding slot. We assume that there will be at most one friend with a given name in the list. You may want to use nested for-loops for this function. Sample calls should look like this. >>> lookup_friends_heights([{"name":"todd","height":170},{"name": "sarah", "height":165},{"name":"dweezil", "height":175}], ["dweezil", "sarah"]) [175, 165] >>> lookup_friends_heights([{"name": "todd","height":170},{"name": "sarah","height":165},{"name": "dweezil", "height":175}], %3D ["sarah", "elíza", "dweezil"]) [165, None, 175]The 'for' loop can iterate over lists in only one direction, from left to right Select one: True False3. lookup_friends_heights This function takes a friends database (a list of dictionaries, like the previous functions) and a list of friends names, and it returns a list of heights for the specified friends.

- The function last_words in python takes one parameter, fname, the name of a text file, and returns a list containing the last word from each line of the file. For example, if the file contents are: apples are red bananas are yellow limes are green then the list ["red", "yellow", "green"] should be returned. NOTE: You may assume the file will contain no blank lines. BIG HINT: If line is a string representing a line of text (inside a for loop!), then L = line.split() creates a list of the words in the line. For example: Test Result L = last_words("wordlist1.txt") print(L) ['happy', 'sad', 'angsty', 'euphoric', 'maudlin']Program Description:in C language The project is a student management system which maintains student records in a simple text file. Your task is to write a program to save a list of students records in a FILE and then perform several operations on this FILE. Your program will ask user to choose the option from a menu. The 3 major function in menu are: ADD STUDENT FIND STUDENT PRINT LIST Exit How it Works The menu is handled by do while and switch statement. Sample output The Methods to be implemented are as follows: 1. ADDSTUDENT This method will add a new student to the file. It takes 3 parameters ( student name, id, and GPA). Your program must ask the user to enter the details of new students: Name, ID and GPA 2. FINDSTUDENT This method will search for a student with his/her id in the file. If the student is found it will print her/his record to the output. If the student is not found it will print “There is no record of this student in this system” 3. PRINTLIST This method will…Program 2: students_result.py Write and execute a Python program to read 10 students marks to process and produce different statistcal output. The program has to ask the user to input marks for 10 students and store them in a list. You can use the following marks as the input for your program. Inputs: 88, 51, 50, 90, 79, 84, 92, 65, 80, 72 You need to find the letter grade for each student's marks based on the conditions shown below. For calculating letter grade, define a programmer-defined function that takes mark as the parameter and return corresponding letter grade. Use the function that to calculate the letter grade for each student and store it in the new list. Mark Grade 90 s mark 80 s mark : : # File Name # Student Id # Student Name Display the output as follows: Marks Grade 88 B 51 F 50 90 A 79 84 92 65 80 72 Average Mark...

- Using a while loop and your is_prime function above, define a list containing the first 100 prime numbers. (The reason a while loop is natural to use here, is because you want to keep searching until you have found 100 prime numbers. You don't know in advance how far you need to search.) Call the list first_primes. PythonPython problem Ask the user to enter their company name to validate it based on the database list(COMPANYLIST). If the user enters invalid inputs (which means it is not in the database list), after the second invalid input, your code should show (print) the list of the company names. #company database listCOMPANYLIST = ["Amazon", "Apple", "Facebook", "Google", "Uber"] Ask the user the rate and the hours and validate them to be a numeric and positive value Save the inputs in a dictionary like theDict = { "rate":50, "hours": 120, "compan_name": "Google"} If "hours" is greater than 40, multiply 1.5 by the rate for the overtime print the pay stub Use modules and import them to the main file Your main file can be like this: from getInputsFile import getInputsfrom computePayFile import computePayfrom printPayFile import printPay def payProcess(): ''' This function is to process all other functions to get inputs, calculate and print the pay stub ''' theDict =…Instructions Create a program that contains a function append_combine(x, a) where x is a list of integers and a is an integer. Aside from appending a to list x , the function should also check if the number at the end of list before appending a are equal. If they are, then these two values should be combined instead. Combining should be done repeteadly until there are no more consecutive pairs in the list. See example below. Example test cases X = [] append_combine(x, 1) # [1] append_combine(x, 2) # -> [1, 2] append_combine(x, 2) # -> [1, 2, 2] -> [1, 4] append_combine(x, 2) # -> [1, 4, 2] append_combine(x, 2) # -> [1, 4, 2, 2] -> [1, 4, 4] -> [1, 8] append_combine (x, 3) # -> [1, 8, 3] append_combine(x, 2) # -> [1, 8, 3, 2] append_combine(x, 4) # -> [1, 8, 3, 2, 4] append_combine(x, 4) # -> [1, 8, 3, 2, 4, 4] -> [1, 8, 3, 2, 8] # Final value of x is [1, 8, 3, 2, 8]
