Groupings

by CodeChum Admin

Did you know that you can also reverse lists and group them according to your liking with proper code? Let's try it to believe it.

Instructions:

Create a variable that accepts a positive odd integer.

Create an empty list. Then, using loops, add random integer values into the list one by one. The number of values to be stored is dependent on the inputted odd integer on the first instruction.

Reverse the order of the list. Then, print out the list's new order in this manner:

[first-half values]-[middle value]-[second-half values], just like that of the sample output. Make use of list slicing that you’ve learned from the past lessons to easily achieve this segment.

Input

The first line contains an odd positive integer.

The next lines contains an integer.

Output

A line containing a list.

[2,5]-[4]-[3,1]

The GCD

by CodeChum Admin

The greatest common divisor, also known as GCD, is the greatest number that will, without a remainder, fully divide a pair of integers.

Now, I want you to make a program that will accept two integers and with the use of loops, print out their GCD. Make good use of conditional statements as well.

Off you go!

Input

A line containing two integers separated by a space.

6·9

Output

A line containing an integer.

Arraying 102

by CodeChum Admin

We've already made arraying/listing the easy way, but how about arraying/listing and printing the list in reverse order?

Make a program that will input an integer and then using loops, add items on an array/list one by one for the same number of times as that of the first inputted integer. Then, print out the array/list in reverse order, that is, starting from the last item on the array/list down to the first one, each in separated lines.

Input

The first line contains the size of the array/list.

The next lines contains the items of the array/list (integers).

 Big-Sightedness

by CodeChum Admin

I got my grandmother a new phone because I thought that we could talk more everyday by texting. Well, let’s just say that my grandma’s eyes aren’t the best anymore so she can’t really see what I text her and because of that she wants to ditch texting and stick with carrier pigeons. You know how embarrassing it is for a kid like me to be seen using carrier pigeons?!?! Well, anyway, I was hoping that you could make a program that takes my text and make it bigger, a LOT bigger. How about you test it out by only using the letters A, B, and C first.

Input

1. My text

Description

This is a string with characters A, B, and C.

Constraints

It is guaranteed that all letters are in uppercase.

Output

The first line will contain a message prompt to input my text.

The succeeding lines will contain the enlarged text.

Enter·my·text:·ABC

***·**··***
*·*·*·*·*
***·**··*
*·*·*·*·*
*·*·**··***

The Positive Ones

by CodeChum Admin

There are different kinds of numbers, but among them all, the most commonly used numbers in our daily lives are those positive ones. So, I only want you to count all the positive numbers from the 4 outputted values and print out the result.

Go and search for the positive ones among these four!

Input

A line containing four numbers (may contain decimal places) separated by a space.

2·-4·3.6·1

Output

A line containing an integer.

5. Negative Decimal Tally

by CodeChum Admin

We've been giving positive numbers too much attention lately, it's time to let negative numbers take the spotlight this time!

Instructions:

1. Input four float numbers; they could be positive or negative.
2. Only add all inputted negative numbers, and print its sum, up to 2 decimal place.
3. Hint: The previous/latest topic is about if-else-elseif statements, but do we need one here?

Instructions

1. Input four decimal numbers, they could be positive or negative.
2. Add all the negative numbers, and print the sum, up to 2 decimal places.

Input

A line containing four decimals/floats separated by a space.

-30.22·10.5·-2.2·-1.8

Output

A line containing a negative decimal/floats with two decimal places.

-34.22

Write pseudo code that prints the smallest value among a list of numbers.

2. Write a subroutine named "printDayofWeek" that will output the day of the week for a given number. Use Swtich-case. For example, the command "1” would output “Sunday”.

3. The Car class (subclass) inherits the attributes and methods from the Vehicle class (superclass). And every car has model. Please also add toString method to the Car class to print out the brand, and model of the car.

Class Vehicle { protected String brand; Vehicle()

{

Brand = “Ford”; }

public void honk() { System.out.println("Tuut, tuut!");

} }

Please help write the Car class.

4. Try to refactor below codes for computing score (underlined part) with extract methods.

// Vehicle attribute

// Vehicle constructor

// Vehicle method

  public class Customer {

void foo() {

int a, b, c, xfactor;

int

}
