Julius Caesar protected his confidential information by encrypting it using a cipher. Caesar's cipher (check Resources tab for more info) shifts each letter by a number of letters. If the shift takes you past the end of the alphabet, just rotate back to the front of the alphabet. In the case of a rotation by 3, w, x, y and z would map to z, a, b and c.

Julius Caesar protected his confidential information by encrypting it using a cipher. Caesar's
cipher (check Resources tab for more info) shifts each letter by a number of letters. If the
shift takes you past the end of the alphabet, just rotate back to the front of the alphabet. In
the case of a rotation by 3, w, x, y and z would map to z, a, b and c.
Create a function that takes a strings (text to be encrypted) and an integer k (the rotation
factor). It should return an encrypted string.

write a function get_intersecting_station(line_one, line_two) where line_one and line_two are the colors of the lines.

Write a function to return a list of the Fibonacci sequence up to x terms The Fibonacci Sequence is a series of numbers. The next number is found by adding up the two numbers before it. The first two numbers are 0 and 1. For example, 0, 1, 1, 2, 3, 5, 8, 13, 21. The next number in this series above is 13+21 = 34. It turns up all over the place in science and nature, and is named for Leaonardo Fibonacci who wrote about it in 1202, but was written about by Pingala (who may have discovered it) in ancient India in 200BC. def fibonacci(n):
We would like to write a collection of functions that do operations on a list of numbers. For example, suppose we write a function max_val. The function takes a list of numbers and returns the maximum value. So, if we passed the list [1,30, 70,-90,80,2] the return value would be 80, since 80 is the maximum number in the list. Here is the list of functions we would like to write: (use basic coding, loops, functions, don't use things like the sum function) 1) max_val, return maximum value. 2) min_val, returns minimum value. 3) mean, returns average. 4) std, returns standard deviation. 5) list_append, adds a new element to the end of the list. 6) list_insert, inserts a new element to the list at a desired location (do not use the insert list function). 7) list_add, adds an inputed number to every value in the list. 8) list_subtract, subtracts an inputed number to every value in the list. 9) list_multiply, multiples an inputed number to every value in the list. 10) list_divide, divides…

We are going to write a program to create a word puzzle. For now, what we need is a function promptletnum that will prompt the user for one letter and an integer in the range from 1 to 5 (inclusive), error-checking until the user enters valid values, and then return them. The function will convert upper case letters to lower case. This function might be called from the following script wordpuz: wordpuz.m (1, n] = promptletnum; fprintf('We will find words that contain the \n') fprintf('letter ''tc'' %d times.\n', 1, n)
Write 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 ('|') 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. Hints: Use the find() function to find the index of a comma in each row of…
Write a python program and add a function named words_and_sents() to it. Thisfunction takes a string parameter called text. Your function should count and print thetotal number of words and sentences in the text. Assume that every word in the text is asubstring followed by a space character “ “. Also, assume that every sentence in the textis a string containing one or more words and must end with a “.” or “?” character. Finally,capitalize each sentence (i.e., convert the first letter to uppercase) and print them onseparate lines. See the sample output below.>>> text = "hello, here are some words. and some sentences. canyou count them.">>> words_and_sents(text)#sentences = 3, #words = 12Printing sentences:Hello, here are some words.And some sentences.Can you count them.
Task 2: The formula for the area, A, of a triangle with sides of length a, b, and c is V[s(s – a)(s – b)(s – c)] A = Where (a + b + c) s = Write, test, and execute a function that accepts the values of a, b, and c as parameters from a calling function, and then calculates the values of s and [s(s - a)(s - b)(s - c)]. If this quantity is positive, the function calculates A. If the quantity is negative, a, b, and c do not form a triangle, and the function should set A = -1. The value of A should be returned by the function. Test the function by passing various data to it and verifying the returned value.
Complete the rotate_text() function that takes 2 parameters, a string data and an integer n. If n is positive, then the function will shift all the characters in data forward by n positions, with characters at the end of the string being moved to the start of the string. If n is 0 then the text remains the same. For example: rotate_text('abcde', rotate_text('abcde', rotate_text('abcde', 1) would return the string 'eabcd' 3) would return the string 'cdeab' 5) would return the string 'abcde' rotate_text('abcde', 6) would return the string 'eabcd' ... and so on. If n is negative, then the function will shift the characters in data backward by n positions, with characters at the start of the string being moved to the end of the string. For example: rotate text('abcde', -1) would return the string 'bcdea'
