Which of the following pairs fill in the blanks to output 6?
❌ A. ArrayList and put(1, 6) ❌ B. ArrayList and replace(1, 6) ✅ C. ArrayList and set(1, 6) ❌ D. HashSet and put(1, 6) ❌ E. HashSet and replace(1, 6) ❌ F. HashSet and set(1, 6) ❌ G. The code does not compile with any of these options.
Explanation: The put() method is used on a Map rather than a List or Set, making options A and D incorrect. The replace() method does not exist on either of these interfaces. Finally, the set method is valid on a List rather than a Set because a List has an index. Therefore, option C is correct.

Telegram has no known backdoors and, even though it is come in for criticism for using proprietary encryption methods instead of open-source ones, those have yet to be compromised. While no messaging app can guarantee a 100% impermeable defense against determined attackers, Telegram is vulnerabilities are few and either theoretical or based on spoof files fooling users into actively enabling an attack.
Newly uncovered hack campaign in Telegram
The campaign, which security firm Check Point has named Rampant Kitten, comprises two main components, one for Windows and the other for Android. Rampant Kitten’s objective is to steal Telegram messages, passwords, and two-factor authentication codes sent by SMS and then also take screenshots and record sounds within earshot of an infected phone, the researchers said in a post published on Friday.
