You have received 2 names.
Verify if the sum of letters of the 1 name is the same as sum of the letters of the 2 name. If the name or surname is null output NULL.
For example:
-
"Anna" and "Nana"
"Anna" = 65+110+110+97 = 382
"Nana" = 78+97+110+97 = 382
Result: "Anna" and "Nana" => "TRUE" -
"Sebastian" and "Patricia" => "FALSE"
-
"John" and null => "NULL"

}Sebastian and Patricia want to know if the sum digits of their years is greater than the sum digits of their mother's years?
Example: (27,3,1)
- Mother = 27
- Sebastian = 3
- Patricia = 1
Calculate: (2+7) < (3+1) => false
