Monoalphabetic-Encryption

In the monoalphabetic substitution encryption, each alphabetic letter is substituted by another letter according to the following table:

Plain text	a	b	c	d	e	f	g	h	i	j	k	l	m	n	o	p	q	r	s	t	u	v	w	x	y	z
Cipher text	q	w	e	r	t	y	u	i	o	p	a	s	d	f	g	h	j	k	l	z	x	c	v	b	n	m

Construct this table and store it in the memory. Write a program that allowed you to enter a plain text message, encrypt this message using the stored table, then decrypt the cipher text to obtain the original text message. Omit any space between words in your message.
