Java program to find the potential of a word is found by adding the ASCII value of the alphabets

The potential of a word is found by adding the ASCII value of the alphabets.

(ASCII values of A to Z are 65 to 90).

Example: BALL

Potential = 66 + 65 + 76 + 76 = 283

Write a program to accept a sentence which may be terminated by either “ . ” , “ ? ” or “ ! ” only. The words of sentence are separated by single blank space and are in UPPER CASE. Decode the words according to their potential and arrange them in ascending order of their potential strength.

Test your program with the following data and some random data:

Example 1:

INPUT: HOW DO YOU DO?

OUTPUT: HOW = 238

DO = 147

YOU = 253

DO = 147

DO DO HOW YOU

Example 2:

INPUT: LOOK BEFORE YOU LEAP.

OUTPUT: LOOK = 309

BEFORE = 435

YOU = 253

LEAP = 290

YOU LEAP LOOK BEFORE

Example 3:

INPUT: HOW ARE YOU#

OUTPUT: INVALID INPUT
