3. Square to the Next Level

by CodeChum Admin

We've already tried printing out the values of an array in reversed order, right? Today, we shall compute for the squares of all the numbers.

There's already a predefined array/list containing 100 integer values. Loop through each values, compute their squares, and display them.

Output

Multiple lines containing an integer.

Search and Rescue

by CodeChum Admin

Make a program that will accept an integer and loop for the same number of times as that of the inputted integer and input random integers and add it to the array/list one by one, per line. Afterwards, make your program accept another random integer.

Using that final integer, compare from your array/list if the final integer's value is also present in your current array/list. If so, print "Present"; otherwise, print "None".

Start coding now!

Input

The first line contains the size of the array/list. The next lines contain the integers. The last line contains an integer to be searched.

Using ArrayList create a book borrowing system. Create ListBook.txt that list all the book information such as bookId, bookTitle, bookAuthor, bookGenre.

• Display all the book available from ListBook.txt
• User can search the book that want to borrow
• count and display how many book user borrow
• display the expected time the user should returned the book

I have to create a book borrowing system by using data structures arraylist. The system include bookId, bookTitle, bookAuthor and genre. There are booklist.txt that have book information - bookId, bookTitle, bookAuthor, genre

1.The system can search the book that user want to borrow by book id or book Title.

2. Ask if the user want to add another book.

3.Count and display the book information that user borrow and the total of the book.

 input 5 numbers and find the min?

I want very simple code

input 5 numbers and calculate sum of the even number

I want very simple code

loops + if combined:

question 1: input 5 numbers and calculate the sum of all numbers?

I think I should use a list of the number

I want very simple code

Function:

question 1:  convert inche-mm
question 2:  convert Celsius-Fahrenheit
question 3:  return max of 3 nums
question 4:  input and combine title+first+last
question 5:  car_rental (dayrate, #days) get discount with >5 dayes , >10 days

I want very simple code for them

Your task is to find the sum of the length of all lines (in kms) that can be drawn between co-ordinates of these countries.

• Assume radius of earth: 6371 km
• Round length of each line and final result to 2 decimal points
• If co-ordinates are missing for any country use 0.000 N 0.000 E

Population limit: 28875

Note: Population limit will change at random intervals. So please make sure answer is computed for the correct population limit before submitting.
