Donot use maths class.Caesars Cypher in C programming language How do you program an encryption and decryption for a Caesars Cypher that covers all the possible ASCII characters? In this there should be a shift over K = 5 but the example below is K = 3. This should result in actual character and not the control ASCII represenations. For example: >>> $ encrypt(I have a key)N%mf{j%f%pj~>>> $ encrypt(see me at 3)xjj%rj%fy%8>>> $ decrpyt(|jfw%ns%gqzj)wear in blue Assume that the text parsing method has been succesful and it's the encryption/decryption of the char array that needs to be factored. Formula Encryption -> C = E(k, P) = (P + k) (mod 26) Decryption -> P = D(k, C) = (C - k) (mod 26) Where k = 5

- Python Write an assert statement that triggers an AssertionError if the variable spam is an integer less than 10. Write an assert statement that triggers an AssertionError if the variables eggs and bacon contain strings that are the same as each other, even if their cases are different (that is, 'hello' and 'hello' are considered the same, and 'goodbye' and 'GOODbye' are also considered the same)To write an application that uses recursion to solve a problem. Details: Create a class called Power that computes the value of base exponent. The class should have one recursive method: • public static int power(int base, int exponent) – Which computes the value of base exponent using recursion, returning the result. The recursion step should use the following relationship base exponent = base x base exponent - 1 and the termination condition should occur when exponent is equal to 1, because base 1 = base NOTE: For the power method, assume the exponent parameter value is always greater than 0. Create a second class called PowerTest that contains the main method, and tests the Power.power method. The test class does not need to ask for input from the user of the class, nor does it need to do any additional error checking. Upload both source files to Blackboard. Note: Ensure that your program is properly formatted and it follows all Java naming conventions.11. Which among the following classes are used in decoding data?
