I want a function to calculate numerology.For example if i enter "XYZ" then my output should be 3 .
Here is how it became 3:
X = 24
Y = 25
Z = 26
on adding it becomes 75 which again adds up to 12 (7+5) which again adds up to 3(1+2) . Similarly whatever names i should pass,my output should be a single digit score.
