The following table represents addition of two six-digit numbers given in the first and the second rows, while the sum is given in the third row. In the representation, each of the digits 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 has been coded with one letter among A, B, C, D, E, F, G, H, J, K, with distinct letters representing distinct digits. $$\newline$$ <img src="https://balti.aftergrad.in/questions/cGRWahPC0K3nJfc" width="400px"/>

According to a coding scheme the sentence $$\newline$$ Peacock is designated as the national bird of India is coded as $\newline$ $5688999351135556678564581366668913347913366$ $$\newline$$ This coding scheme has the following rules: $$\newline$$ 1. The scheme is case-insensitive (does not distinguish between upper case and lower case letters). $$\newline$$ 2. Each letter has a unique code which is a single digit from among $1,2,3, \ldots, 9$. $$\newline$$ 3. The digit $9$ codes two letters, and every other digit codes three letters. $$\newline$$ 4. The code for a word is constructed by arranging the digits corresponding to its letters in a non-decreasing sequence.
