import java.util.Arrays; public class Main { public static void main(String []args){ int[] random = { 6, -4, 100, 12, 0, -10 }; int x = 12; int y = Arrays.binarySearch(random, x); System.out.println(y); } }
❌ A. 2 ❌ B. 3 ❌ C. 4 ❌ D. 6 ✅ E. -3 ❌ F. An exception is thrown. ❌ G. The code does not compile
Explanation: The code compiles and runs fine. However, an array must be sorted for binarySearch() to return a meaningful result. If it is not sorted, the results are undefined.

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.
Mr. Durov launched Telegram in late 2013 with his brother, Nikolai, just months before he was pushed out of VK, the Russian social-media platform he founded. Mr. Durov pitched his new app—funded with the proceeds from the VK sale—less as a business than as a way for people to send messages while avoiding government surveillance and censorship.
