Write pseudocode for a function that translates a telephone number with letters in it (such as 1-800-FLOWERS) into the actual phone number. Use the standard letters on a phone pad.

Explanation:

Function telToNumbers with one parameter of a String input for the telephoneNumber

String var newTelephoneNum;

for loop through telephoneNumber {

Char var currentChar = current Character in the loop;

currentChar to lower Case;

Switch statement (currentChar) {

 case "a" or "b" or "c" : newTelephoneNum += "2"; break;

 case "d" or "e" or "f" : newTelephoneNum += "3"; break;

 case "g" or "h" or "i" : newTelephoneNum += "4"; break;

 case "j" or "k" or "l" : newTelephoneNum += "5"; break;

 case "m" or "n" or "o" : newTelephoneNum += "6"; break;

 case "p" or "q" or "r" or "s" : newTelephoneNum += "7"; break;

 case "t" or "u" or "v" : newTelephoneNum += "8"; break;

 case "w" or "x" or "y" or "z" : newTelephoneNum += "9"; break;

 default : newTelephoneNum += currentChar; break;

 }

}

print newTelephoneNum;
