Round 2 (Technical Round – 1 hour 15 minutes): My interview was scheduled for 45 mins but it went for 1 hour 15 minutes.

- Question – Bit manipulation – Write a code to replace the 3rd bit in a binary number 10100 such that the answer is 10000.
Given x = 10100 Take a = 00100 as we have to switch the third bit. Now ~a = 11011 x AND a = 10100 & 11011 = 10000 ans.
