I want to work on this issue.@Mohit-Mithra @Z0Marlin

[him1anshu]

the input will be in uppercase and without spaces by default or it can also take input in lowercase and with spaces then it should do the conversion after changing the input into uppercase and without spaces?@Mohit-Mithra @Z0Marlin

[z0marlin]

@him1anshu Go ahead! The input will have alphanumeric characters and white spaces. It can also have punctuations and special characters. The Cipher should only operate on the alphabets though, i.e. [ a-z] and [A-Z].

Eg: This is an EXAMPLE input for issue #193.
