Using a Java program solve the following problem using arrays: Past A: Coupon collector is a classic statistic problem with many practical applications. The problem is to pick objects from a set of objects repeatedly and determine how many picks are needed for all the objects to be picked at least once. A variation of the problem is to pick cards from a shuffled deck of 52 cards repeatedly and find out how many picks are needed before you see one of each suit. Assume a picked card is placed back in the deck before picking another. Write a program to simulate the number of picks needed to get total of four cards from each different suit and display the four cards picked (it is possible that a card may be picked twice). Here is a sample run of the program: Queen of Spades 5 of Clubs Queen of Hearts 4 of Diamonds Number of picks: 12 Sample run explanation: As you see in the above run, 12 picks are made to get the four cards from different suits. The other 8 picks (12-4-8) were from the same previously picked suits, so they are not printed. So we continue picking a card until we see at least one card from each of the for suits. Note: The card pick is with replacement, meaning that when you pick a card from the deck of 52 card, you put it back in the deck. There is chance to see the previously selected card again. Part B: Put part A in a for loop and repeat it 10,000 times and report the average number of total picks we should have to see 4 cards from different suits.

Python Algorithm Question (similar to celebrity Python problem). Having trouble implementing the algorithm. Here's the question: Let’s say you’re going to invite some people to a party. You’re considering n friends, but you knowthat they will only have a good time if each of them knows at least k others at the party. (Assume that if A knows B, then B automatically knows A.) Solve your problem by designing an algorithm for finding the largest possible subset of your friends where everyone knows at least k of the others, if such a subset exists. To help you get started I’ve made a graph of "my friends": G={'Rachel':['Ross','Monica'], 'Ross':['Rachel','Monica'], 'Monica':['Rachel','Ross'], 'Jon Snow':['Daenerys','Sansa','Arya'], 'Daenerys':['Jon Snow','Sansa','Arya','Khal Drogo'], 'Sansa':['Jon Snow','Daenerys','Arya'], 'Arya':['Jon Snow','Daenerys','Sansa'], 'Khal Drogo':['Daenerys'], 'Cersei':['Jaime'], 'Jaime':['Cersei'], 'Bart':['Milhouse'], 'Milhouse':['Bart','Lisa'],...

A basic iterator offers all the following operations except Group of answer choices 1. Except nothing, it can do all of the listed operations. 2. Get the item at the current iteration 3. Return an array of all items 4. Determine if there are more items 5. Go to the next item

A popular word game involves finding words from a grid of randomly generatedletters. Words must be at least three letters long and formed from adjoining letters.Letters may not be reused and it is valid to move across diagonals. As an example,consider the following 4 * 4 grid of letters: A B C DE F G HI J K LM N O P The word "FAB" is valid (letters in the upper left corner) and the word "KNIFE"is valid. The word "BABE" is not valid because the "B" may not be reused. Theword "MINE" is not valid because the "E" is not adjacent to the "N". Write a program that uses a 4 * 4 two-dimensional array to represent the gameboard. The program should randomly select letters for the board. You may wishto select vowels with a higher probability than consonants. You may also wish toalways place a "U" next to a "Q" or to treat "QU" as a single letter. The programshould read the words from the text file words.txt (included on the website withthis book) and then use a recursive algorithm to...

Start with a pile of n stones and successively split a pile into two smaller piles until each pile has only one Each time a split happens, multiply the number of stones in each of the two smaller piles. (For example, if a pile has 15 stones and you split it into a pile of 7 and another pile of 8 stones, multiply 7 and 8.) The goal of this problem is to show that no matter how the pile of n stones are split, the sum of the products computed at each split is equal to n(n - 1)/2. Using strong mathematical induction, prove that no matter how the pile of n stones are split, the sum of the products computed at each split is equal to n(n - 1)/2.

Design and implement a recursive program(in java) to determine and print the Nth line of Pascal's triangle, as shown below. Each interior value is the sum of the two values above it. Hint: Use an array to store the values on each line.

JAVA PROGRAM Write a program that asks the user to input two integers a and b. Then create an array that has all integer from a to b. Print out the array. (Don’t forget to consider the situation of a=b, a<b, and a>b.) Example 1: Input two numbers: 6 2 Array is [6, 5, 4, 3, 2] Example 2: Input two numbers: 4 8 Array is [4, 5, 6, 7, 8] Pass the above array as a parameter to a method called average and return the average and print it out in the main method. (Do not use Math library to get the average.)
