Write a program that translates a letter used in a telephone number into an equivalent numeric digit. The program asks the user to enter a letter, translates the letter into the corresponding digit and displays it. The user may enter its selection either as an upper or lower case letter.

The program translates the letter into a digit according to the table below:

j k l 5

m n o 6

p q r s 7

t u v 8

w x y z 9
