Three problems utilizing OOP with recursion, classes, inheritance, assertions, and more.

MIT OCW 6.0001 Problem Set 4

Three problems utilizing OOP with recursion, classes, inheritance, assertions, and more:

Part A

Part A is a recursive algorithm that returns the permutations (O/N!) of a given input string.

Part B

Part B is an improved Caesar Cypher with modular classes and subsequent inheritance that can both encrypt and decrypt messages.

Part C

Finally, Part C utilizes Part A's permutation algorithm to build a Substitution Cypher that replaces vowels in a message with a corresponding permutation of vowels.
