MidPath hiring

You are given a string variable called 'original'. You need to write a javascript program that uses this variable and assignes a new value to another variable called 'computed' according to the given rules.

If the character is a digit, leave it unchanged. If the position of the character is a multiple of 3 then rotate the character by 5. If the position of the character is a multiple of 5, rotate it by 9. However, if the character's position is a multiple of both 3 and 5, rotate it by 3. If none of these conditions are satisfied, rotate the character by 2.

In order to rotate a character, say 'k' by an amount of 4 we need to find the character 4 places before 'k' in alphabetical order which turns out to be 'g'. Consider only lowercase a-z characters and assume that they are cyclic in nature.
