JustPerfects.java (for Loop). In this program, you will use loops to identify perfect numbers (a number equal to the sum of its divisors - 6 and 28 are the first two! 6 is 2 +3 + 1 and 28 is 14+7+4+2+1). Being the perfect number is quite unique. Only 4 perfect numbers exist between 1 and 10,000 and you’ve already found two! Please write a program to find the additional pair. Bonus: How many perfect numbers exist between 10,000 and...

In Yahtzee, 5 standard dice are rolled up to three times on a given turn. A player can choose to save anywhere from 0 - 5 of the dice between rolls 1 and 2 and between rolls 2 and 3, meaning that the player can set aside certain dice before rolling the remaining dice if they choose to do so. Suppose that a given player does not take advantage of saving die rolls and instead rolls all 5 dice each...
