Design a Logger with Configurable Message Processing (remove substring / truncate / uppercase / store-only)

Problem: Implement a Configurable Logger (OOD) Implement a Logger that can process an input log message message according to a configured behavior, and then either print to stdout or store internally. Supported behaviors: Remove: remove all occurrences of a configured substring pattern before printing. Truncate: truncate the message to at most maxLen characters before printing. Uppercase: convert the entire message to uppercase before printing. Store-only: do not print; store messages in an internal list. Requirements Use a reasonable OOD design (e.g., Strategy/Decorator/Chain of Responsibility) so that adding new behaviors requires minimal/no changes to existing code. Provide a way to construct/configure the logger (constructor or factory), including needed parameters (e.g., pattern, maxLen). For non-store behaviors, print the processed message to stdout. For store-only, do not print; only store. Examples Remove(pattern="ab"), input "ab12ab3" -> prints "123" Truncate(maxLen=4), input "hello" -> prints "hell" Uppercase, input "Hello" -> prints "HELLO" Store-only, input "hello" -> prints nothing; internal storage appends "hello" Constraints message contains printable ASCII characters. pattern is non-empty. maxLen >= 0. Sample tests Remove("ab") + ab12ab3 => stdout: 123 Truncate(4) + hello => stdout: hell Uppercase + Hello, world! => stdout: HELLO, WORLD! Store-only + msg1, msg2 => stdout: (none), stored: ["msg1","msg2"] Truncate(0) + abc => stdout: `` Example Input remove ab ab12ab3 Output 123
