Chapter 3, Problem 8PP

In a certain code language, numerals are each represented by a symbol or a letter.

They are as follows

Numerals are to be coded as per the codes in the table and the following conditions:

a. If the first and the last digits are odd, both are to be coded as 'X'.

b. If the first and the last digits are even, both are to be coded as $\text{'\$'}\text{.}$

c. If the last digit is '0', it is to be coded as $\text{'}\#\text{'}.$

For example, 487692 is coded as $\text{\$R\%KM\$}$

Write a program that takes as input a sequence of numbers and displays the corresponding code to represent it.
