+Calculate the total score (sum of the individual character scores) of a sentence given the following score rules for each allowed group of
+characters:
+
+1. Lower case [a-z]: 'a'=1, 'b'=2, 'c'=3, ..., 'z'=26
+2. Upper case [A-Z]: 'A'=2, 'B'=4, 'C'=6, ..., 'Z'=52
+3. Digits [0-9] their numeric value: '0'=0, '1'=1, '2'=2, ..., '9'=9
+4. Other characters: 0 value
+
+*Note: input will always be a string*
