Pseudo-code · Question 25 · Medium

What will be the output of the following pseudocode? (Note: &, ^ and >> are bitwise AND, XOR and right shift.)

Integer a, b
Set a = 29, b = 15
Print (a & b) ^ (a >> 1)
  1. 13
  2. 3
  3. 27
  4. 1
Answer and explanation

Answer: B. 3

Explanation: 29 & 15 = 11101 & 01111 = 01101 = 13, and 29 >> 1 = 14 (01110). 13 ^ 14 = 01101 ^ 01110 = 00011 = 3.
