Analyze the cipher table

We need to map each character of the coded message back to its original alphabet letter using the provided table.

• The top row represents the original Alphabet (including the exclamation mark '!').
• The bottom row represents the corresponding Code character.
• To decode, we find each character of the coded message in the Code row and replace it with the character directly above it in the Alphabet row.

Decode the first word "Csy"

Let's find each letter of "Csy" in the Code row:

• 'C' in Code corresponds to 'Y' in Alphabet.
• 's' (case-insensitive 'S') in Code corresponds to 'O' in Alphabet.
• 'y' (case-insensitive 'Y') in Code corresponds to 'U' in Alphabet.
• Thus, "Csy" decodes to "You".

Decode the second word "higshih"

Let's find each letter of "higshih" in the Code row:

• 'h' in Code corresponds to 'D' in Alphabet.
• 'i' in Code corresponds to 'E' in Alphabet.
• 'g' in Code corresponds to 'C' in Alphabet.
• 's' in Code corresponds to 'O' in Alphabet.
• 'h' in Code corresponds to 'D' in Alphabet.
• 'i' in Code corresponds to 'E' in Alphabet.
• 'h' in Code corresponds to 'D' in Alphabet.
• Thus, "higshih" decodes to "decoded".

Decode the third word "qi1"

Let's find each character of "qi1" in the Code row:

• 'q' in Code corresponds to 'M' in Alphabet.
• 'i' in Code corresponds to 'E' in Alphabet.
• '1' in Code corresponds to '!' in Alphabet.
• Thus, "qi1" decodes to "me!".

Combine the decoded words

Combining the decoded parts gives: "You decoded me!".
