Question

Read in a time such as 3 pm and print the equivalent military hour (such as 15). Validate the input.

If the input doesn’t start with an integer, print: Error: Not an integer.
If the number isn’t between 1 and 12, print: Error: The hour must be between 1 and 12.
If the suffix isn’t "am" or "pm", print: Error: The suffix must be am or pm.

## Converting Standard Time to Military Time Using Java

In this lesson, you will learn to write a Java program that reads in a time such as "3 pm" and prints the equivalent military hour (such as "15"). The program includes input validation to ensure that users input the time correctly.

### Requirements
- **Valid Input**: The program expects an integer followed by either "am" or "pm".
- **Input Validation**:
- If the input doesn’t start with an integer, prints: `Error: Not an integer.`
- If the number isn’t between 1 and 12, prints: `Error: The hour must be between 1 and 12.`
- If the suffix isn’t "am" or "pm", prints: `Error: The suffix must be am or pm.`

### TimeReader.java

```java
import java.util.Scanner;

public class TimeReader
{
public static void main(String[] args)
{
Scanner in = new Scanner(System.in);

if (in.hasNextInt())
{
int hour = in.nextInt();

if (hour >= 1 && hour <= 12)
{
String suffix = in.next();

if (suffix.equals("am") || suffix.equals("pm"))
{
// Convert hour to military time
if (suffix.equals("pm") && hour != 12)
{
hour += 12;
}
else if (suffix.equals("am") && hour == 12)
{
hour = 0;
}

System.out.println(hour);
}
else
{
System.out.println("Error: The suffix must be am or pm.");
}
}
else
{
System.out.println("Error: The hour must be between 1 and 12.");
}
}
else
{
System.out.println("Error: Not an integer.");
}
}
}
```

### Explanation

1. **Importing Scanner**:
```java
import java.util.Scanner;
```
The `Scanner` class is imported to allow reading user input from the console.

2. **Class Definition**:
```java
public class TimeReader
```
The class `TimeReader` is defined to encapsulate the program logic.

3. **Main Method**:
```java
public static void main(String[]

In CORAL LANGUAGE please and thank you! Summary: Given integer values for red, green, and blue, subtract the gray from each value. Computers represent color by combining the sub-colors red, green, and blue (rgb). Each sub-color's value can range from 0 to 255. Thus (255, 0, 0) is bright red, (130, 0, 130) is a medium purple, (0, 0, 0) is black, (255, 255, 255) is white, and (40, 40, 40) is a dark gray. (130, 50, 130) is a faded purple, due to the (50, 50, 50) gray part. (In other words, equal amounts of red, green, blue yield gray). Given values for red, green, and blue, remove the gray part. Ex: If the input is: 130 50 130 the output is: 80 0 80 Hint: Find the smallest value, and then subtract it from all three values, thus removing the gray.

Your program will prompt the user for the following information: current population number of yearly births from the previous year number of yearly deaths from the previous year number of years into the future for your predictive value of the future population. You will then compute the following: birth rate death rate growth rate the predicted future population Assignment Notes: To allow the user to input the numeric data (such as current population) it is necessary to use the input function. The input function takes a string in parenthesis that prompts the user what to enter. The computer then waits until the user types a response, terminated by the user typing the Enter key. A string, as a sequence of characters, is returned to the variable on the lefthand side of the assignment statement. For example: currPopulation = input(“Enter the current US population”) The data in currPopulation is a string (because that is what the input statement does) but we need it to be a number…

This code must be in Python: START OF PLAY The player starts with 100 points. They have ten attempts (or rounds) to reach 500 points to win. Each round, the player "bets" some amount of points. See gameplay as follows: A HIGH/LOW ROUND (1) The player is shown an initial random card.Cards have a value from 2-14; however, these values are converted to a string as follows: 2-9 are converted to their string equivalent "2", "3", ... "9"10 is "T", 11 is "J", 12 is "Q", 13 is "K" and 14 is "A" (2) After the play sees the first card, they should guess if the next card will be higher (i.e., greater than the current card) or lower (i.e., a lower value than the first card).They will do this by inputting "H" or "L" (lowercase "h" and "l" will also be accepted as valid input). (3) After they input their "high" or "low" guess, the player bets a number of points that their guess will be right. The bet must be between 1 and the total amount of points the player has.1 (4) After the bet amount is…

Scenario As you surely know, due to some astronomical reasons, years may be leap or common. The former are 366 days long, while the latter are 365 days long. Since the introduction of the Gregorian calendar (in 1582), the following rule is used to determine the kind of year: if the year number isn't divisible by four, it's a common year, otherwise, if the year number isn't divisible by 100, it's a leap year. otherwise, if the year number isn't divisible by 400, it's a common year. otherwise, it's a leap year. none of the above year int(input("enter the year")) if (year%4 1-0) and (year%400 -0) or (year % 1000): print (year is common year") else: print(year, is leap year") year= int(input ("enter the year")) if (years !-0) or (year480 1-0) and (year % 1001-0): print(year is common year") else: print(year, "is leap year") D year= int(input("enter the year"))
-scripting language Write a program that randomly generates a lottery between 100 and 999 (random.randint(100, 999)), prompts the user to enter a number in the same range, and determines whether the user wins according to the following rule: (1) If the user input matches the lottery in exact order, print "the award is $10,000". E.g., lottery = 123, input = 123(2) If the user input matches the lottery, but in wrong order, print "the award is $6,000". E.g., lottery = 123, input = 321(3) If two digits in the user input matches a digit in the lottery, print "the award is $3,000". E.g., lottery = 123, input = 612(4) If one digit in the user input matches a digit in the lottery, print "the award is $1,000". E.g., lottery = 123, input = 289(5) If none of the digits is matched, print "thank you".
Exercise III: Catalan numbers For n e N, denote by c, to be the number of ways to form a "mountain range" with n upstrokes (U) and n downstrokes (D) that all stay above a horizontal line. For instance: for n = 1, only UD is allowed, so c = 1; • for n = 2, only UUDD and UDUD are allowed, so c2 = 2. 1. Check that c3 = 5 by writing down or drawing all possible options. 2. Consider the power series +00 g(x) = 2 n=0 (by definition co = 1) called the generating function of the sequence (en). Justify that cn < 4" for each n, and deduce that the radius of convergence of g is at least 1/4. 3. It can be show that for r E (-1/4, 1/4), g(x) = 1+ xg(r)? and therefore 1- VI 4.x g(x) = 2.x Use this formula and the known power series of V1+ x to write the first terms of the power series expansion of g, in the form g(x) = co + c1x + c2x2 + C3x + c4x* + ·.. Show how you obtain a few terms, but you do not need to show all computations and you can use a calculator for fractions. Check that you recover co,…
