13. The reciprocal Fibonacci constant y is defined by the infinite sum:Σ.where F, are the Fibonacci numbers 1, 1, 2, 3, 5, 8, 13, ... . Each element inthis sequence of numbers is the sum of the previous two. Start by setting thefirst two elements equal to 1, then F, = F-1+ Fn-2. Write a MATLAB pro-gram in a script file that calculates y for a given n. Execute the program forn = 10, 50, and 100.14.

8.In this exercise you will create a program that will be used in a digital library to format and sort journal entries based on the authors last name. Each entry has room to store only the last name of the author. Begin by removing the first name "Isaac" from the string variable journal_entry_1 by using the string function erase. Do not forget to also remove the whitespace so that the string variable journal_entry_1 will then contain the string "Newton" with no whitespaces. The journal entries should be sorted alphabetically based on the authors last name. For example, the last name "Brown" should come before the last name "Davis" Create an if statement so that if the last name contained within journal_entry_2 is alphabetically less than the last name contained within journal_entry_1, then the string values are swapped using the string function swap. You may use either of the comparison operators < > in the if statement but remember that following ASCII, "A" is lexicographically…

PYTHON I have a file name KindOfNumbers.csv In that csv file there are these numbers: 2, 3, 6, 8, 9, 13, 16, 15, 28, 97, 64, 67, 59, 100, 128, 496, 386 893 4567, 843, 894, 935, 974, 863, 991. In PYTHON, After reading the data from the csv file, CREATE THE FOLLOWING LISTS FROM GIVEN NUMBERS: _PRIME NUMBERS _PERFECT NUMBERS _ODD NUMBERS _EVEN NUMBERS ***EACH LIST SHOULD BE SORTED. ***WRITE THE ARRAYS, INCLUDING THE SORTED ORIGINAL, TO A FILE WITH APPROPRIATE DESCRIPTION INCLUDING THE NUMBERS OF VALUES IN THE ARRAY.
A Canadian postal code is a six-character alphanumeric string that represents a part of a postal address. They are in the format of A1A 1A1, where A could be any letter and 1 could be any number from 0-9. Given an unsorted list of postal codes, write a Python program, in a file call postal.py, to sort the list of postal codes (actually modify the given list into a sorted list) and then display the sorted postal codes such that each postal code with the same starting letter is printed on the same line, with each line in alphabetical order. Note that the postal codes can be in any order on the same line, as long as they all start with the same letter, or you can have them sorted on the line as well. For example, given the following list of postal codes: postal_codes = ['A1A 1A1', 'B3K 5X5', 'V9A 7N2', 'A0Z 6P7', 'H0H 0H0', 'A1B 1T0'] The output would be similar to: Sorted postal codes: A0Z 6P7 A1A 1A1 A1B 1T0 B3K 5X5 H0H 0H0 V9A 7N2 Note: You are not permitted to use the sort() method.

Exercise 11.10. Two words are “rotate pairs” if you can rotate one of them and get the other (see rotate_word in Exercise 8.12). Exercise 8.12. ROT13 is a weak form of encryption that involves “rotating” each letter in a word by 13 places. To rotate a letter means to shift it through the alphabet, wrapping around to the beginning if necessary, so ’A’ shifted by 3 is ’D’ and ’Z’ shifted by 1 is ’A’. Write a function called rotate_word that takes a string and an integer as parameters, and that returns a new string that contains the letters from the original string “rotated” by the given amount. For example, “cheer” rotated by 7 is “jolly” and “melon” rotated by -10 is “cubed”. You might want to use the built-in functions ord, which converts a character to a numeric code, and chr, which converts numeric codes to characters. Potentially offensive jokes on the Internet are sometimes encoded in ROT13. If you are not easily offended, find and decode some of them. Please solve Exercise 11.10 -…

can you please solve the question and make it in the right format so that I can copy and paste it? Write a program that reads a list of words. Then, the program outputs those words and their frequencies. The input begins with an integer indicating the number of words that follow. Assume that the list will always contain less than 20 words. Ex: If the input is: 5 hey hi Mark hi mark the output is: hey 1 hi 2 Mark 1 hi 2 mark 1 Hint: Use two vectors, one vector for the strings and one vector for the frequencies. 272772.1571588
c++ , A character string is given. What is the minimum number of characters you need to change to make the resulting string of identical characters? Solve this task in 3 different manners using : sets, maps and deque ( 3 different codes ) Input output 69pop66 4 1+2=12 4
python: Open the file mbox-short.txt and read it line by line. When you find a line that starts with 'From ' like the following line:From stephen.marquard@uct.ac.za Sat Jan 5 09:14:16 2008 You will parse the From line using split() and print out the second word in the line (i.e. the entire address of the person who sent the message). Then print out a count at the end. Hint: make sure not to include the lines that start with 'From:'. Also look at the last line of the sample output to see how to print the count. You can download the sample data at http://www.py4e.com/code3/mbox-short.txt my code: fname = input("Enter file name: ")if len(fname) < 1: fname = "mbox-short.txt" fh = open(fname)count = 0 print("There were", count, "lines in the file with From as the first word")
A. The original Caesar cypher shifts each character by one: a becomes b, z becomes a, and so on. Let's make it a bit harder, and allow the shifted value to come from the range 1..25 inclusive. Moreover, let the code preserve the letters' case (lower-case letters will remain lower-case) and all non-alphabetical characters should remain untouched. Your task is to write a program which: asks the user for one line of text to encrypt; asks the user for a shift value (an integer number from the range 1..25 - note: you should force the user to enter a valid shift value (don't give up and don't let bad data fool you!) Test your code using the data we've provided. Test data Sample input: abcxyzABCxyz 123 2 Sample output: cdezabCDEzab 123 Sample input: The die is cast 25 Sample output: Sgd chd hr bzrs
