/*
 Asked by - Delta X

Given two strings,Multiply each letter's positional value (i.e A=1,B=2,..,Z=26) with other letters within the string.
After performing the multiplication,apply mod(47) to the values and return "SAME" if both values else return "NOT SAME".

Example:
 Input : string 1 = ABC
         string 2 = XYZ

Output : NOT SAME
