Given a program that reads an arbitrary amount of integers between 0 - 50 from the user.

 Your program should count the number of times each number was entered. Indicate the end of the user input by a value outside of the range. 

After all input has been processed, print all of the values (with the number of occurrences) that were entered one or more times

 Sample output: If the user enters 0 0 1 45 49 49 49 100

 

4. Given the following list of numbers [14, 17, 13, 15, 19, 10, 3, 16, 9, 12] What is the contents of the array after the second partition has occurred, according to the quicksort algorithm?

 

5. Write a file merge program There are two files numbers1.txt and numbers2.txt. Both of these files contain 500 integers (one integer per line). The integers in each file are sorted in nondescending order. Your program should read in the numbers from these files. Your program should then create a new output file. This file should contain the contents of the two input files, of the integers, still sorted in non-descending order 

Challenge: try to do it without using built in sorts (i.e., don't just pour everything into one array and call sort) 

Hint: you will probably want to create helper methods, and yes, there are exactly 500 ints in each file. 

 

6. a method called rollDie that simulates the rolling of a single dice, i.e., returns a random number between 1 and 6.

 Write a method that checks to see if the roll has won in the game of craps. ◦ 

• A loss is when the dice roll a 2, 3, or 12 ◦
• A win is when the dice roll 7 or 11 ◦
• All other numbers are a "tie"

Now wrote a main program that asks the user to bet whether the dice are going to "win" or "lose", and then roll a pair of dice using the rollDie method The program should then display what was rolled, check to see if the user bet correctly, and report the results

 

7.Give a method that accepts a string, str, and an integer, count, as parameters. The method should return a string that consists of str concatenated with itself count times. 

ex. passing in "test" and 4, your method would return "testtesttesttest" /

Now overload your method so that if the integer parameter is not provided, the method returns the string concatenated with itself once ◦ ex. passing in "test" returns "test.
