Programming & Computer Science Answers

Example:

Base integer = 3

Initial factor = 2

Number of times to process = 3

Process:

1.) 2 x 3 = 6

2.) 6 x 3 = 18

3.) 18 x 3 = 54

Therefore, the output would above would be 54.

Instructions:

1. In the code editor, you are provided with a main() function that asks the user for the 3 integer inputs required for this program and calls the getResult().
2. This getResult() function has the following details:
3. Return type - int
4. Name - getResult
5. Parameters
6. int - Base integer
7. int - Initial factor
8. int - Number of times to process
9. Description - this is a recursive function which implements the desired behavior explained in the problem description
10. The getResult() function is partially implemented already. Your only task is to add the correct recursive case.

1. In the code editor, you are provided with a main() function that asks the user for a string and passes this string and the size of this string to a function call of the function, preserveString().
2. This preserveString() function has the following description:
3. Return type - void
4. Name - preserveString
5. Parameters
6. The string
7. Length of the string
8. Description - this is a recursive function that prints the string repeatedly. Each time it prints the string, it excludes the last character of the string until only one character is left.
9. This preserveString() function has already been partially implemented. Your only task is to add the recursive case of this function.

Write a complete Java program illustrating the difference between instance and static members of class. Indicate with comments where each is used and explain the significance of making the instance or static. (6 marks)

Making use of object orientation write a program that stores and evaluates the total cost for items bought from a supermarket. The cashier should enter the following: - Product code, Price and Quantity. The total price should be evaluated as follows: -

Total cost = Price * Quantity

If the total cost per item is more than 20,000 there is a discount of 14% on that item and a discount of 10% on an item whose total cost is between 10,000 and 20,000. No discount is given on items whose total cost is less than 10,000

Did you know that in lotteries, a 3-digit number with the same numbers in all digits like 777 will hit the jackpot in a casino? In the same manner, let's make a program that will test if a certain 3-digit number hits a jackpot or not by identifying if all the digits of a given number is the same as the second inputted number. If it is, print "Jackpot!"; else, print "Nah".

Let's try this out now!

Input

A line containing two integers separated by a space.

777·7

Output

A line containing a string.

Jackpot!

A teacher in a class with N students has noticed that some students have formed their own groups and hence prevented intermingling of students to get those students to mix with each other, the teacher has decided a seating pattern.The seating pattern is very simplistic viz. every boy should sit next to a girl and every girl should next to a boy. They are all seated in one line. It is also mandatory that no two boys sit together, and no two girls sit together. Your task is to make the above happen with minimum number of swaps between as-is situation to desired solution

ATM PIN Code Validation

Write a function with the name validate atm.pin code that takes a word as an argument. ATM PIN is considered valid only if the given word contains Exactly 4 or 6 characters - All the characters should be digits.

Input

The input will be a single line containing a string.

Output

The output should be a single line containing either "Valid PIN Code or "Invalid PIN Code".

Explanation

For example, if the given word is "9837". the output should be "Valid PIN Code", as it contains exactly four characters and all the characters are digits.

Whereas, if the given word is "A289h4", the output should be "invalid PIN Code, though the given word contains exactly six characters, all the characters are not digits.

Write a program that prints all the uppercase characters of the ASCII character table. Display 5 characters per line. Characters are separated by exactly one space.
