Solution #41058677 by usmiwka80 for problem 01. Galactic Code Decryption

Problem 1 – Galactic Code Decryption

Welcome codebreaker. You have been recruited by the Galactic Federation to assist in deciphering transmissions intercepted from a mysterios alien civilization. These coded messages are crucial for understanding their technology and intentions. Your mission is to modify these transmissions using a set of decryption commands until the command "Finalize" is given.

You are provided with a coded message in the form of a string. Until receiving the command "Finalize" you must process this string using various commands to manipulate and decode the message. Each command will alter the message in a specified manner:

• "Encrypt"
  • Reverse the order of the characters in the message.
  • Print the message.
• "Decrypt"
  • Swap the case of all characters in the message (uppercase to lowercase, lowercase to uppercase).
  • Print the message.
• "Substitute {old_char} {new_char}"
  • Replace all occurrences of the specified character {old_char} (case-sensitive!) with the character {new_char}.
  • Print the message.
  • If {old_char} is not found, print: "Character not found.".
• "Scramble {index} {char}"
  • Replace the character at the specified index with {char}.
  • Print the message.
  • If the index is out of range, print: "Index out of bounds.".
• "Remove {substring}"
  • Delete all instances of the specified substring from the message (case-sensitive!) .
  • Print the message.

If a command that does not match any of the above is received, print "Invalid command detected!".

Input / Constraints

• The first line will contain the initial coded message as a string.
• Subsequent line will contain commands until the "Finalize" command is encountered.
• All commands are case-sensitive.

Output

• Print the output of the commands in the format described above.
