Write a program that asks the user for 3 numbers. Return the product of these 3 numbers multiplied together. If the user puts in less than 3 numbers, return 0; If the user puts in more than 3 numbers, only multiply the first 3. If the number is not a number, default that value to 1.

• Example:

The product of these 3 numbers is: 480
Hint: Consider using the split method

• Tests:

  • Input a string of numbers and it returns a product of all numbers
  • Input more than 3 numbers
  • Input of less than 3 numbers
  • Can it handle negative numbers

Create a method that asks the user to enter a number between 2-10. Then, prompt the user that number of times for random numbers.

After the user has inputted all of the numbers. Find the average of all the numbers inputted.

Specs: 1. Do not let the user put in negative numbers 2. Confirm each input is a real number

Example:

1 of 4 - Enter a number: 4
2 of 4 - Enter a number: 8
3 of 4 - Enter a number: 15
4 of 4 - Enter a number: 16
The average of these 4 numbers is: 10

• Tests:

  • Input different ranges of numbers and confirm averages
  • Confirm input
  • All numbers are 0s

Create a method that will output to the console the following design. Pay attention to spacing.

    * 
   *** 
  *****
 *******
*********
 *******
  *****
   ***

  • No tests are required

Write a method that brings in an integer array and returns the number that appears the most times. If there are no duplicates, return the first number in the array. If more than one number show up the same amount of time, return the first found.

 Example: Input: [1,1,2,2,3,3,3,1,1,5,5,6,7,8,2,1,1]
 output: 1

• Tests:

  • Input different size arrays
  • All numbers in the array are the same value
  • No duplicates exist in the array
  • There multiple numbers that show up the same amount of times.

Write a method in that finds the maximum value in the array. The array is not sorted. You may not use .Sort()

Example: input [5, 25, 99, 123, 78, 96, 555, 108, 4]
return: 555

• Tests:
  • Negative numbers
  • All values are the same

Write a method that asks the user to input a word, and then saves that word into an external file named words.txt

• Hint: Have a file already saved in the root of your directory with a couple of words already present in the file.

  • Tests are optional for this challenge

Write a method that asks the user to input a sentence and returns an array that with the word and the number of characters each word has:

• Example:

Input: "This is a sentance about important things"
Output: ["this: 4","is: 2", "a: 1", "sentance: 8", "about: 5", "important: 9", "things: 6"]

• Tests:
  • Input a sentance, and it returns the correct array
  • Inut a sentance and confirm it returns an array
  • Use different sentances with differnt symbols
