a)

Program Plan Intro

To create a moveBubble() method which moves the bubble across the bubble box, this method accepts two argumentsheight and width which represent height and width of the object and declaring variables, bubbletop equal to the value of the yPos property, bubblebottom equal to the sum of the yPos and radius properties, bubbleLeft equal to the value of the xPos property, and bubbleRight equal to the sum of the xPos and radius properties.

b)

Program Plan Intro

To declare a conditional if statement inside the moveBubble() method,for the bubbletop if it is less than zero or bubbleBottom is greater than the height argument, then the bubble has hit the top or bottom wall and if the condition is trure then changing the direction of the vertical velocity by letting this.yVelocity equal this.yVelocity.

c)

Program Plan Intro

To declare a conditional if statement inside the moveBubble() method, for the bubbleLeft is less than zero or bubbleRight is greater than the width argument, the bubble has hit the left or right wall and if the condition becomes true then changing the direction of the horizontal velocity by letting this.xVelocity equal this.xVelocity.

d)

Design a dynamic programming algorithm for the Longest Alternating Subsequence problem described below: Input: A sequence of n integers Output: The length of the longest subsequence where the numbers alternate between being larger and smaller than their predecessor The algorithm must take O(n²) time. You must also write and explain the recurrence. Example 1: Input: [3, 5, 4, 1, 3, 6, 5, 7, 3, 4] Output: 8 ([3, 5, 4, 6, 5, 7, 3, 4]) Example 2: Input: [4,7,2,5,8, 3, 8, 0, 4, 7, 8] Output: 8 ([4, 7, 2, 5, 3, 8, 0,4]) (Take your time with this for the subproblem for this one)

Design a dynamic programming algorithm for the Coin-change problem described below: Input: An amount of money C and a set of n possible coin values with an unlimited supply of each kind of coin. Output: The smallest number of coins that add up to C exactly, or output that no such set exists. The algorithm must take O(n C) time. You must also write and explain the recurrence. Example 1: Input: C24, Coin values = = [1, 5, 10, 25, 50] Output: 6 (since 24 = 10+ 10+1+1 +1 + 1) Example 2: Input: C = 86, Coin values = [1, 5, 6, 23, 35, 46, 50] Output: 2 (since 86 = 46+35+5)

Design a dynamic programming algorithm for the Longest Common Subsequence problem de- scribed below Input: Two strings x = x1x2 xm and y = Y1Y2... Yn Output: The length of the longest subsequence that is common to both x and y. . The algorithm must take O(m n) time. You must also write and explain the recurrence. (I want the largest k such that there are 1 ≤ i₁ < ... < ik ≤ m and 1 ≤ j₁ < ... < jk ≤ n such that Xi₁ Xi2 Xik = Yj1Yj2 ··· Yjk) Example 1: Input: x = 'abcdefghijklmnopqrst' and y = 'ygrhnodsh ftw' Output: 6 ('ghnost' is the longest common subsequence to both strings) Example 2: Input: x = 'ahshku' and y = ‘asu' Output: 3 ('asu' is the longest common subsequence to both strings)
