The Fibonacci sequence begins with 0 and then 1 follows. All subsequent values are the sum of the previous two, ex: 0, 1, 1, 2, 3, 5, 8, 13.
Complete the fibonacci() function, which has an index n as parameter and returns the nth value in the sequence. Any negative index values
should return -1.
Ex: If the input is:
7
the output is:
fibonacci (7) is 13
Note: Use a for loop and DO NOT use recursion.

- Computer Science Write a program that processes a data sequence according to the following specifications: The sequence has three kinds of positive numbers: red, black and white. Each red number is preceded by the letter r, each black number is preceded by the letter b and each white number is preceded by the letter w. The number 0 indicates the end of data. If a number is preceded by any character other than r, b or w, the number is ignored. For instance, if the input to the program is: r 23 b 15 b 11 w 17 c 13 r 19 b 0, then we have two red numbers, 23 and 19, two black numbers 15 and 11, and one white number, 17. The number 13 is ignored. (The terminating 0 is also a black number but it is not processed.) The program produces the following output: The sum of red numbers is 42The sum of black numbers is 26The sum of white numbers is 17 Assume that input is from the keyboard and is in the prescribed format.

The ith invocation of the resulting function will generate the value: start + step * i. The first invocation is said to be the 0th. Examples var x = sequence( 3, 15 ) [ x(), x(), x() ] => [ 3, 18, 33 ] var y = sequence( 28, -5 ) [ y(), y(), y() ] => [ 28, 23, 18 ]arrow_forwardDefine a function named check_game_finished (encrypted_list) which takes a list of characters as a parameter. The function returns True if the game is over, and False otherwise. The game is over when there is no longer any "*" characters in the parameter list.

- Write a function, Decode() that can analyse a list of card numbers. The function is constructed as follows:The function receives the string list (as in Question 3.1) as parameter and returns no value to the calling statement.When this function executes the following should happen:Each card number in the list should be analysed in turn to extract the encoded information in the following format:0318241215528881: Was issued by Diner’s club in 2018. The card expires on 24/12. The card is linked to a Credit account with account number: 15528881.It may be assumed that any year (YY) refers to the years 2000+.The information for each card number must be stored in one string variable. The variable must then be sent to the WriteFile() function (see Question 3.3 below) so that the result can be saved. The process repeats until each card number in the list is sent to the WriteFile() function.arrow_forwardIn python, rite a recursive function, displayFiles, that expects a pathname as an argument. The path name can be either the name of a file or the name of a directory. If the pathname refers to a file, its filepath is displayed, followed by its contents, like so: File name: file_path Lorem ipsum dolor sit amet, consectetur adipiscing elit... Otherwise, if the pathname refers to a directory, the function is applied to each name in the directory, like so: Directory name: directory_path File name: file_path1 Lorem ipsum dolor sit amet...

- PART 1: Find the Nth Fibonacci Number (Objective - 4)You will implement a function for finding the nth Fibonacci number using the MIPS assembly language. Following gives the definition of the Fibonacci Sequence. Your code should comply with the coding conventions described in the lectures.Let F be the Fibonacci function:F(0) = 0F(1) = 1For n > 1 F(n) = F(n-1) + F(n-2)Example Output of Execution:Enter the sequence number: 6F(6) = 8 A - Loop ImplementationIn a file named FiboLoop.asm, implement the above function using a loop. B - Recursive ImplementationIn a file named FiboRec.asm, implement the above function using a loop. PART 2: Evaluating Execution Time (Objective - 1)A) Complete the following table. Provide how many instructions of the given categories are executed while finding the F(6) for both loop and recursive functions, seperately. You should provide two tables, one for non-recursive the other for recursive function. B) Then calculate the total clock cycles for each…arrow_forwardWrite a program that reads movie data from a CSV (comma separated values) file and output the data in a formatted table. The program first reads the name of the CSV file from the user. The program then reads the CSV file and outputs the contents according to the following requirements: • Each row contains the title, rating, and all showtimes of a unique movie. • A space is placed before and after each vertical separator (I) in each row. • Column 1 displays the movie titles and is left justified with a minimum of 44 characters. . If the movie title has more than 44 characters, output the first 44 characters only. • Column 2 displays the movie ratings and is right justified with a minimum of 5 characters. • Column 3 displays all the showtimes of the same movie, separated by a space. Each row of the CSV file contains the showtime, title, and rating of a movie. Assume data of the same movie are grouped in consecutive rows. Ex: If the input of the program is: movies.csv and the contents of…arrow_forwardThe Fibonacci sequence begins with O and then 1 follows. All subsequent values are the sum of the previous two, for example: 0, 1, 1, 2, 3, 5, 8, 13. Complete the Fibonacci() function, which has an index n as a parameter and returns the nth value in the sequence. Any negative index values should return -1.

- For example, the number 35190 can be cut between 351 and 90 digits, from 3 + 5 + 1 = 9 and 9 + 0 = 9. On the other hand, the number 555 has no place to rest (you must divide between digits). Create a retrieval function if the number has a breakpoint, and is false if not. Examples break_point (159780) - true break_point (112) - true break_point (1034) - true break_point (10) lie break_point (343) – liearrow_forwardMutual Exclusion: Select all of the following statements that are true. The Peterson Algorithm does not rely on the mechanism of busy waiting. The Peterson Algorithm is a purely software-based solution to the mutual exclusion problem. The only way to guarantee the atomicity of operations is to disable interrupts. Mutex Locks are an API offered by operating systems to protect critical sections. In order to enter a critical section protected by Mutex Locks, the release() operation must be executed first. The test_and_set instruction is atomic.arrow_forwardwith python do whis: Edit or delete a user profileWhen the user chooses 2, the first thing that it should do is to check whether the user information is loaded in the program (i.e., check if the user information is passed to the function that generates recipe recommendations). If the user information is passed to the function (i.e., the user chose option 1 before choosing option 2), the program should show the user the following menu:Hello (user name)You can perform one of the following operations:1) Delete your profile2) Edit your profilea. If the user chooses 1, perform the following subtasks to delete a user profile:1- Search for the user profile in the file userInformation.txt using the user name in read mode; once you find the user profile (i.e., the line that contains all the user information), pass it to a function that deletes the user information.2- The function should create a temporary file called temp.txt in write mode and search the file userInformation.txt in read mode…arrow_forward
