write an algorithm that store old massage and get an new message, do an AND operation for the two message index from two array, first array index is old message id, second array index is the new message id, if the compare result is not zero then return true, otherwise return false
write an algorithm that stores an old message and gets a new message, do an AND operation for the two message indexes from two arrays, the first array index is the old message ID, the second array index is the new message ID, if the compare result is not zero then return true, otherwise, return false
Initialize Variables: Create an array oldMessages to store old message IDs. Create an array newMessages to store new message IDs.
Function storeOldMessage(id): Append id to oldMessages.
Function compareMessages(newId): For each oldId in oldMessages: Perform AND operation: result = oldId & newId. If result != 0, return true. If no matches found, return false.
initialize oldMessages as empty array initialize newMessages as empty array function storeOldMessage(id): append id to oldMessages function compareMessages(newId): for each oldId in oldMessages: result = oldId & newId if result != 0: return true return false
storeOldMessage(5) // oldMessages = [5] storeOldMessage(10) // oldMessages = [5, 10] result = compareMessages(5) // returns true (5 & 5 = 5) result = compareMessages(3) // returns false (5 & 3 = 1, 10 & 3 = 2)
