Assignment 1: Due Date: Thursday, April. 29, 2021 1 What you need to do Write a program in your preferred programming language that will ask the user to enter any plaintext. Then, it will encrypt/decrypt the string using substitution cipher and print out the results on the screen. Encryption should be based on the following conditions: • Replace the characters at the string's odd positions with the previous character located in the English alphabet. • Replace the characters at the string's even positions with the 10th letter after in the English alphabet. 2 What to Submit You should submit your code and a technical report, which explains your experience developing the program.

hideshow Write a function hideshow that accepts two string arguments, an input string and a masking string. The masking string is a string consisting of '0's and '1's that has the same length as the input string. The function then returns a new string that is the same as the input string, except that it is masked. That is, in any position where the masking string contains a '0' the input character is replaced by a '#', whereas if the masking string contains a '1', the character is unchanged. Sample usage: >>> hideshow('apple', '11001') 'ap##e' >>> hideshow('apple', '00000') '#####' >>> hideshow('apple', '11111') 'apple' >>> hideshow('abcdefghijklmnopqrstuvwxyz', 13*'01') '#b#d#f#h#j#1#n#p#r#t#v#x#z' >>> hideshow 'df###re##', '101010101' ) 'd#####e##' >>> hideshow( 'df###re%%', '101010101' )=='d#####e##' True

Q1: Write a program that asks the user to enter their first name and their last name,separated by a space. Break the input string up into two strings, one containing thefirst name and one containing the last name. You can do that by using the indexOf()subroutine to find the position of the space, and then using substring() to extracteach of the two names. Also output the number of characters in each name andoutput the user’s initials. (The initials are the first letter of the first name togetherwith the first letter of the last name.) A sample run of the program should looksomething like this:Please enter your first name and last name, separated bya space.? Mary SmithYour first name is Mary, which has 4 charactersYour last name is Smith, which has 5 charactersYour initials are MS
