How to get gibberish:
1. Take the receipt and remove all white spaces, punctuation and new lines. [optional: remove "and" as well] This will be called RECEIPT.
2. For each char x in "waknbodxtzyxdjnnl" {
int y = 0;
For all x in RECEIPT {
y+=x.position; // x.position is the index of the character in the String
}
y=y mod26;
Convert y to Letter;
Add y to solution;
}
