Let $x, y$ be two nonnegative integers $< 2^{32}$. By $x \wedge y$ we mean the integer represented by the bitwise logical $AND$ of the 32 bit binary representations of $x$ and $y$. For example, if $x = 13$ and $y = 6$, then $x \wedge y$ is the bitwise ... code for the input $x = 13$? What will be the output of the pseudocode for an arbitrary nonnegative integer $x < 2^{32}$?

In the code fragment on the right, start and end are integer values and $prime(x)$ is a function that returns true if $x$ is a prime number and $false$ otherwise. At the end of the loop: i := 0; j := 0; k := 0; for (m := start; m <= end; m := m+1){ k := k + m; if (prime(m)){ i := i + m; }else{ j := j + m; } } $k < i+j$ $k = i+j$ $k > i+j$ Depends on $start$ and $end$

For example 7/3 returns 2 since 2 is the quotient and 1 is the remainder. mystery(a,b){ if (b == 0) return a; if (a < b) return mystery(b,a); if ... of recursive calls to $mystery$ on input $a,\: b$ is $O(n)$ $O(log log n)$ $O(log n) $O(n^{\frac{1}{2})$

The operator & considers its arguments in binary and computes their bit ... of $n$. The code might go into an infinite loop for some $n$. The result depends on the number of bits used to store unsigned integers.

The program prints $\frac1 2 \times \text{gcd}(X, Y)$ followed by $\frac1 2 \times \text{lcm}(X, Y)$. The program does none of the above.
