❌ A. 11 ❌ B. 13 ❌ C. 23 ✅ D. 36 ❌ E. 50 ❌ F. The code will not compile because of line 7
Explanation: Prior to the first iteration, m = 9, n = 1, and x = 0. After the iteration of the first loop, m is updated to 8, n to 3, and x to the sum of the new values for m + n, 0 + 11 = 11. After the iteration of the second loop, m is updated to 7, n to 5, and x to the sum of the new values for m + n, 11 + 12 = 23. After the iteration of the third loop, m is updated to 6, n to 7, and x to the sum of the new values for m + n, 23 + 13 = 36. On the fourth iteration of the loop, m > n evaluates to false, as 6 < 7 is not true. The loop ends and the most recent value of x, 36, is output, so the correct answer is option D.

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.
