evelop a single program using a python programming language that: a. Encrypts and decrypts a message using the Cesar’s Cipher. The user encrypting the message is prompted to enter a message and then a key that indicates the displacement. The user decrypting the message is prompted to enter the encrypted message and the key. b. Decrypts and displays all (26) possible solutions

Computer Science Write a Java program that reads a line and a line segment and then determines whether they intersect or not. When they overlap completely, consider that as intersecting. Use variables ((lp1x, lp1y), (lp2x, lp2y)) to represent a line and ((sp1x, sp1y), (sp2x, sp2y)) to represent a line segment

Write a structured (procedural) Python program that solves the following spec: Soundex System Coding: Soundex is a system that encodes a word into a letter followed by three numbers that roughly describe how the word sounds. Therefore, similar sounding words have the same four-character code. Use the following set of (slightly modified #4) rules to create a translator from English words to Soundex Code: 1. Retain the first letter of the word. 2. For letters 2 .n, delete any/all occurrences of the vowels (3,elo.u), h, w, y. 3. Assign the following numbers to any remaining letters in the word a. 1 for occurrences of B, F, P, V. b. 2 for occurrences of C, G, J, K, Q, S, X, z C. 3 for occurrences of D, T d. 4 for L e. 5 for M, N f. 6 for R 4. For repeated numbers, remove the repeats ("PROGRAMMING" → P6265552 → P62652) 5. Keep only the first four characters of what you have left (P62652 → P626) However, if you have less than 4 characters, O fill the empty spots so that ALL words have…

Write a program to handle a user's rolodex entries. (A rolodex is a system with tagged cards each representing a contact. It would contain a name, address, and phone number. In this day and age, it would probably have an email address as well.) Typical operations people want to do to a rolodex entry are: 1) Add entry 2) Edit entry 3) Delete entry 4) Find entry 5) Print all entries 6) Quit You can decide what the maximum number of rolodex entries is and how long each part of an entry is (name, address, etc.). When they choose to edit an entry, give them the option of selecting from the current rolodex entries or returning to the main menu — don't force them to edit someone just because they chose that option. Similarly for deleting an entry. Also don't forget that when deleting an entry, you must move all following entries down to fill in the gap. If they want to add an entry and the rolodex is full, offer them the choice to return to the main menu or select a person to overwrite. When…

Write a program using python that continues accepting user inputs as float numbers until the input is an empty string (i.e., a user press Enter without any typing as the input), and then the program will print the largest number among the inputs. If no input is given, print an empty line.
