Consider a computer system with a byte-addressable primary memory of size 2³² bytes. Assume the computer system has a direct-mapped cache of size 32 KB (1 KB = 2¹⁰ bytes), and each cache block is of size 64 bytes.

The size of the tag field is ______ bits.

Consider the following undirected graph with edge weights as shown:

The number of minimum-weight spanning trees of the graph is ______

Consider the following sequence of operations on an empty stack.

push(54); push(52); pop(); push(55); push(62); s = pop();

Consider the following sequence of operations on an empty queue.

enqueue(21); enqueue(24); dequeue(); enqueue(28); enqueue(32); q = dequeue();

The value of s + q is ______

Consider a dynamic hashing approach for 4-bit integer keys:

1. There is a main hash table of size 4.

2. The 2 least significant bits of a key is used to index into the main hash table.

3. Initially, the main hash table entries are empty.

4. Thereafter, when more keys are hashed into it, to resolve collisions, the set of all keys corresponding to a main hash table entry is organized as a binary tree that grows on demand.

5. First, the 3^rd least significant bit is used to divide the keys into left and right subtrees.

6. to resolve more collisions, each node of the binary tree is further sub-divided into left and right subtrees based on 4^th least significant bit.

7. A split is done only if it is needed, i. e. only when there is a collision.

Consider the following state of the hash table.

Which of the following sequence of key insertions can cause the above state of the hash table (assume the keys are in decimal notation)?
