Two 5 cent coins is the optimal solution and Another algorithm approach is Dynamic programming Algorithm.
What is Greedy algorithm?
A greedy algorithm is a method of problem-solving that chooses the best choice at the time. It is unconcerned with whether the most excellent result at the moment will produce the final best result. Even if the choice was the wrong one, the algorithm never goes back and changes its mind. It functions in a top-down manner.
What is Dynamic programming Algorithm?
Every number in a fibonacci series is equal to the sum of the two numbers before it. For instance, 0, 1, 1, 2, and 3. Each of these numbers is the sum of the two numbers that came before it.
a)Example: 1 cent , 5 cents and 7 cents.
The aforementioned example shows that the greedy algorithm does not produce the best result because, if n=10, the solution would be to choose a 7 cent coin and three 1 cent coins, making a total of four coins. This occurs as a result of the greedy method, which gives the greatest currency denomination feasible at a time.
The best course of action, however, is to take two 5 cent coins.
b)Dynamic programming algorithms are another method to algorithms that are utilized to identify the best solution in the aforementioned case.

The brain influence your emotions, thoughts, and values as it rejects sensory signals. The correct option is A.
What are sensory signals?A sensory activation tends to occur when a physical or chemical stimulus is processed by a sensory receptor into a neural signal (sensory transduction).
Chemical messengers such as serotonin and dopamine are used to send signals across the network.
These signals are received by brain regions, resulting in us recognizing objects and situations, assigning emotional value to them to guide behavior, and making split-second risk/reward assessments.

What is a network?A network is a collection of two or more computers or other electronic devices that are linked together to exchange data and share resources.
It should be noted that 145.98 = 10010001.01100010
Then there are 2^(32-16) = 2^16 addresses possible. The range of addresses is from 145.98.0.1 to 145.98.255.255
If there are 2 subnets, 1 bit will be used for the subnet. So each subnet will have 2^32-17 = 2^15 addresses.
For subnet 1 range of IP shall be 145.98.0.1 to 145.98.127.255

Formal parameters in method headers require including the data type for each parameter in source code.
a. true
b. false
Answer: Option A) True
Explanation:
Let's take an example:
public static int min (int a, int b)
{
if (a <= b)
return a;
else
return b;
}
We divide method into two parts: header and body.
The method header comprises the access modifiers (public static), return type (int), method name (min), and parameters (int a, int b); if this method threw any exceptions, they would appear next.The method body is a block-statement that immediately follows the method header. The parameter names are like variable names; in fact, we often call them parameter variables to make this similarity explicit.When a method is called, its parameter variables are always initialized by matching arguments first. Then, the method body executes, using these values to compute and return its result; it can also any local variables declard in the block to help in its computation.
If we wrote the statement
System.out.println( Math.min(3,5) );
it would display 3. If we had declared int x = 3, y = 8; and wrote the statement
System.out.println(Math.min (3*x+5,y) );
it would display 8
If we wrote the statement
System.out.println( Math.min(3,5) );
it would display 3. If we had declared int x = 3, y = 8; and wrote the statement
System.out.println(Math.min (3*x+5,y) );
it would display 8
Generally, We call a method by writing its name, followed in parentheses by its arguments (one for each parameter in the method's header) As in the header (where parameters are separated by commas), arguments are are separated by commas as well. When we call a method, Java first evaluates each argument (each can be a simple or complicated expression) and transmits or passes it to its matching parameter; this just means that Java uses each argument's value to initialize it matching parameter in the method. It is equivalent to writing first-parameter = first-argument, then second-parameter = second-argument, etc.
Thus, when calling Math.max(3*x+5,y) above, the first parameter (a) is initialized by the value 14 (3*x+5: the equivalent of a = 3*x+5). Likewise, the second parameter (b) is initialized by the value 8 (y: the equivalent of b = y). Then, Java executes the body of the method, which typically performs some computation using these initialized parameters. It finally returns a result.

having poor software development practices and failing to program input validation checks during development of custom software can result in a system vulnerable to which type of attack?
Poor software development practices, such as failing to program input validation checks during custom software development, can expose a system to a buffer overflow attack.
What is a Buffer overflow vulnerability?
Attackers take advantage of buffer overflow issues by overwriting an application's memory. This alters the program's execution path, resulting in a response that damages files or exposes private information. An attacker, for example, may insert extra code into the application, sending new instructions to gain access to IT systems.
If an attacker knows a program's memory layout, they can intentionally feed input that the buffer cannot store and overwrite areas that contain executable code with their own code. To gain control of a program, an attacker can, for example, overwrite a pointer (an object that points to another area in memory) and point it to an exploit payload.

The correct instruction for creating an array a of 20 elements of double is int a[n];.
What is an array?
An array is a group of related data elements kept in close proximity to one another in memory. The sole way to retrieve each data element directly is by using its index number, making it the most basic data structure.
There is no need to declare separate variables for each subject, for example, if we wish to keep a student's grades across five disciplines. Instead, we can create an array that will keep the data pieces in close proximity to one another in memory.
The high-precision floating-point data or numbers are stored using the C double data type (up to 15 to 17 digits). Large decimal number values are stored there. The amount of data that can be stored in values is double what can be stored in float data. It is called a double data type as a result.

x.500 lite is an open protocol, so applications don't need to worry about the type of server hosting the directory
the difference between sftp and ftps is : SFTP builds on secure shell protocol (SSH) and adds on file transfer capabilities. FTPS builds on file transfer protocol (FTP) and adds on a security and encryption layer. so the statement "secure ftp (sftp) uses ssl or tls to encrypt commands, while secure ftp (ftps) is an entire protocol itself" is considered inappropriate
the meaning of X.500 Protocol is : a protocol (among others) for a client application to access the X. 500 directory. Called the Directory Access Protocol (DAP), it is layered on top of the Open Systems Interconnection (OSI) protocol stack.
the difference between POP3 and IMAP is : POP3 is an abbreviation for Post Office Protocol. IMAP is an abbreviation for Internet Message Access Protocol. The POP is an Internet standard protocol on the application layer that the local email clients use for retrieving emails from any remote server over the TCP/IP connection. so the statement "pop3 is a remote email storage service responsible for incoming email, while imap is a store-and-forward service for incoming email." is considered inappropriate
for the another option, "snmpv1 uses community strings that support authentication, while snmpv3 use community strings that support encryption" it's False because SNPMv3 is the concept of an authentication service (view-based access control) , and SNMPv1 is a framework that control an access and called SNMP MIB view
