The statement is true. Subproblems in the divide-and-conquer strategy are unrelated to one another. So, it is impossible to take use of overlapping subproblems.

The key concept here is that because our divide and conquer problem has overlapping sub-problems, caching of sub-problem solutions becomes feasible, allowing memoization/tabulation to enter the picture. The CLRS definition of optimal substructure reads: "a problem exhibits optimal substructure if an optimal solution to the problem contains within it optimal solutions to sub-problems." Popular algorithmic paradigm dynamic programming uses a recurring formula to determine the answer. Given that the challenge is divided into smaller sub-problems, it is comparable to the divide and conquer method. Sub-problems are interdependent in dynamic programming, which is the main difference.

Alice cannot deny sending the message if she signs it with her private key, and transmits it to Bob, and Bob then uses Alice's public key to verify the signature.

The area of cryptographic systems that use pairs of related keys is known as public-key cryptography, also known as asymmetric cryptography.

A public key and its accompanying private key make up each key pair. Cryptographic algorithms that are based on one-way functions are used to create key pairs.

The private key must be kept hidden in order for public-key cryptography to be secure; nevertheless, security is not compromised if the public key is freely distributed.

Anyone with access to a public key can encrypt a message in a public-key encryption system, creating a ciphertext.

However, only those who have access to the associated private key can decrypt the ciphertext to reveal the original message.

So, in the given situation, if Alice uses her private key to sign the message and sends it to Bob, Bob can use Alice's public key to confirm the signature, so Alice cannot claim not to have sent the message.

Therefore, Alice cannot deny sending the message if she signs it with her private key, and transmits it to Bob, and Bob then uses Alice's public key to verify the signature.

A way to send secure messages over the internet is Virtual Private Network (VPN)

A virtual private network (VPN) extends a private network to a public network, allowing users to send and receive data over a shared or public network as if their computing device were directly connected to the private network. Benefits of a VPN include improved functionality, security, and management of your private network. Provides access to resources not accessible on public networks and is typically used for remote workers. Encryption is common, although not an integral part of a VPN connection.

A VPN is created by establishing a virtual point-to-point connection over an existing network using a leased line or tunneling protocol. Available over the public Internet, VPNs can offer some of the benefits of wide area networks (WANs).

The name of the tool that ships with Windows and lets you partition a disk and format a file system is the Disk Management tool. It is accessed through the Control Panel or by right-clicking on the My Computer or This PC icon and selecting "Manage". The Disk Management tool allows you to create, delete, and format partitions on your hard drive, as well as assign drive letters and format the file system.

The overall speedup of the system due to the disk upgrade is 60%.

The speedup of the system due to the disk upgrade can be calculated as follows:

First, let's calculate the amount of time the system spends waiting on I/O disk service before the upgrade:

Time waiting on I/O disk service before upgrade = 40% * Total time = 40% * 1 = 0.4

Next, let's calculate the amount of time the system spends waiting on I/O disk service after the upgrade, assuming the disk provides 150% greater throughput:

Time waiting on I/O disk service after upgrade = 40% * 1 / (1 + 150%) = 40% * 1 / 2.5 = 16%

The overall speedup of the system due to the disk upgrade can now be calculated as follows:

Overall speedup = 1 - Time waiting on I/O disk service after upgrade / Time waiting on I/O disk service before upgrade = 1 - 16% / 40% = 1 - 0.4 = 60%

Therefore, the overall speedup of the system due to the disk upgrade is 60%.

Full Question = Suppose a malloc implementation returns 8-byte aligned addresses and uses an explicit free list where the next and previous pointers are each 32-bits. Blocks have a 32-bit header and 32-bit footer, where the low-order bit of the header and footer are used to indicate whether the block is allocated (1) or free (0). Furthermore, the block size (which includes the header, payload, footer, and any necessary padding) is rounded up to the nearest multiple of 8, and this size (in bytes) is stored in the header and footer. Assume any padding must be between the payload and the footer.

Answer: &

Explanation: In some programming languages like C, the ampersand (&) is known as the address operator.

An ampersand is used to denote the unary operator known as the address-of operator (&).

To find the memory address of any variable in your script, use the address operator, a unary operator. There should be no space between the operator and the variable name. The address operator can be used to send a variable's address as a parameter in a function call or to assign the address of a variable to a pointer variable. The address may be sent to C applications, who can then use it just like any other normal C pointer.

The C++ language has a technique called an address-of operator that yields a variable's memory address. These addresses that the address-of operator returns are referred to as pointers since they "point" to the memory location of the variable. Because it provides a reference to a variable by referencing its memory location, the & is known as the reference operator. The * operator, which dereferences a reference, offers us the value pointed to by a pointer. This allows us to access the value rather than the address of a memory location.

Therefore, The unary operator known as the address-of operator is shown by an ampersand (&).
