Answer:
b. The constructor for the parent class is called.
Explanation:
In this case this specific piece of code is calling the constructor for the parent class. Since a MountainBike object is being created. This creation uses the MountainBike class constructor but since this is a subclass of the Bicycle class, the super() method is calling the parent class constructor and passing the variables startCadence, startSpeed, startGear to that constructor. The Bicycle constructor is the one being called by super() and it will handle what to do with the variables inputs being passed.
Write a function int checkBalance(char exp[]); that can take an expression as input and check whether the parenthesis used in that expression are valid or invalid. It returns 1 if it is valid, and returns 0 if it is not valid.For example, the following expressions are valid: [ A * {B (C D)}] and [{()()}]The following expressions are invalid: [ A * {B (C D})], [ { ( ] ) ( ) }
Answer:
Explanation:
The following code is written in Java. It uses for loops to loop through the array of characters, and uses IF statements to check if the symbols in the expression are balanced. If so it returns true, otherwise it breaks the function and returns false. Two test cases have been provided in the main method and the output can be seen in the attached image below.
import java.util.ArrayList;
class Brainly {
public static void main(String[] args) {
char[] exp = { '[', 'A', '*', '{', 'B', '(', 'C', 'D', ')', '}', ']'};
char[] exp2 = {'[', 'A', '*', '(', 'C', '}', ']'};
System.out.println(checkBalance(exp));
System.out.println(checkBalance(exp2));
}
public static boolean checkBalance(char exp[]) {
ArrayList<Character> symbols = new ArrayList<>();
for (char x: exp) {
if ((x =='[') || (x == '{') || (x == '(')) {
symbols.add(x);

How many fingers do you need to type floor
Answer:
About 0-1 fingers at minimum
Explanation:
you can type with your toes/elbow as well. Any body part really.
To type the word "floor" on a regular keyboard layout, you would generally need six fingers: three on your left hand and three on your right.
Your index finger (usually used for the "F" key) on your left hand would be utilised for the letter "f." Your middle finger (which is normally used for the "D" key) would be utilised for the letter "l."
Finally, your ring finger (which is normally used for the "S" key) would be utilised for the letter "o."
Your index finger (usually used for the "J" key) on your right hand would be utilised for the letter "o." Your middle finger (which is normally used for the "K" key) would be utilised for the second letter "o."
Finally, your ring finger (which is normally used for the "L" key) would be utilised for the letter "r."
Thus, on a typical keyboard layout, you would type the word "floor" with three fingers from each hand.

Carl is planning for a large advertising campaign his company will unveil. He is concerned that his current e-commerce server farm hosted in a public cloud will be overwhelmed and suffer performance problems. He is researching options to dynamically add capacity to the web server farm to handle the anticipated additional workload. You are brought in to consult with him on his options. What can you recommend as possible solutions
Answer:
Cloud Bursting
Explanation:
One of the best possible solutions for this scenario would be Cloud Bursting. This is a solution of using Cloud Server services to handle the server farm workload. The difference is that Cloud Bursting allows the company to use the Cloud services only when their own personal web server farms hit peak demand and can no longer handle the incoming demand. The excess demand is outsourced to the Cloud Server and lets them handle it dynamically without the company having to add any additional hardware to their server farm.

g 1-4 Which piece of network hardware breaks a network up into separate collision domains within a single broadcast domain
Answer:
A switch
Explanation:
A local area network (LAN) refers to a group of personal computers (PCs) or terminals that are located within the same general area and connected by a common network cable (communication circuit), so that they can exchange information from one node of the network to another. A local area network (LAN) is typically used in small or limited areas such as a set of rooms, a single building, school, hospital, or a set of well-connected buildings. Some of the network devices or equipments used in a local area network (LAN) includes an access point, personal computers, a hub, a router, printer, a switch, etc.
In computer networking, a switch is a network hardware (device) that breaks up a network into separate collision domains within a single broadcast domain. Thus, it's commonly configured with virtual local area network (VLAN) to break up and interconnect multiple networks.
Create and configure databases in oracle database management system operation administration
Answer:
You typically create a database during Oracle Database software installation. However, you can also create a database after installation.
Reasons to create a database after installation are as follows:
You used Oracle Universal Installer (OUI) to install software only, and did not create a database. You want to create another database (and database instance) on the same host computer as an existing Oracle database. In this case, this chapter assumes that the new database uses the same Oracle home as the existing database. You can also create the database in a new Oracle home by running OUI again. You want to make a copy of (clone) a database.
A recursive method may call other methods, including calling itself. Creating a recursive method can be accomplished in two steps. 1. Write the base case -- Every recursive method must have a case that returns a value or exits from the method without performing a recursive call. That case is called the base case. A programmer may write that part of the method first, and then lest. There may be multiple base cases.Complete the recursive method that returns the exponent of a given number. For e.g. given the number 5 and the exponent 3 (53) the method returns 125. Note: any number to the zero power is 1. Note: Do not code for the example. Your method must work for all given parameters! Use this as your method header: public static int raiseToPower(int base, int exponent)
Answer:
Explanation:
The following code is written in Java. It creates the raiseToPower method that takes in two int parameters. It then uses recursion to calculate the value of the first parameter raised to the power of the second parameter. Three test cases have been provided in the main method of the program and the output can be seen in the attached image below.
class Brainly {
public static void main(String[] args) {
System.out.println("Base 5, Exponent 3: " + raiseToPower(5,3));
System.out.println("Base 2, Exponent 7: " + raiseToPower(2,7));
System.out.println("Base 5, Exponent 9: " + raiseToPower(5,9));
}
public static int raiseToPower(int base, int exponent) {
if (exponent == 0) {
return 1;
} else if (exponent == 1) {
return base;
} else {
return (base * raiseToPower(base, exponent-1));
}
}

Add (total) all the number in the list (below) using a for loop, but skip over the number at index 3.
numbers = [10,20,30,40,50,60,100]
Answer:
The program in Python is as follows:
numbers = [10,20,30,40,50,60,100]
total = 0
for i in range(len(numbers)):
if i != 3:
total+=numbers[i]
print(total)
Explanation:
This initializes the list
numbers = [10,20,30,40,50,60,100]
Set total to 0
total = 0
This iterates through numbers
for i in range(len(numbers)):
This ensures that the index 3, are not added
if i != 3:
total+=numbers[i]
Print the calculated sum
print(total)

Explanation:
A computer with a five-stage pipeline deals with conditional branches by stalling for the next three cycles after hitting one. How much does stalling hurt the performance if 20% of all instructions are conditional branches
Answer:
The stalling hurt the performance by 60%.
Explanation:
This can be calculated as follows:
Value of CPI ideally taken by pipeline = 1
From the question, we are given:
Stall frequency = 20%,
Number of frequency = 3
Therefore, we have:
Cycles per instruction (CPI) of the architecture = Value of CPI ideally taken by pipeline + (Stall frequency * Number of frequency) = 1 + (20% * 3) = 1.60
Amount by which the stalling hurt the performance = Cycles per instruction (CPI) of the architecture Value of CPI ideally taken by pipeline = 1 - 0.60 = 0.60, or 60%
Therefore, the stalling hurt the performance by 60%.
