The entries aij of matrix A are computed according to the formula aij =1 for i=1, j>1, aij=0 for i>1, j=1, aij = (ai-1,j + ai,j-1)/2 for i>1, j>1.(i) Estimate the number of operations + that are necessary to compute aij. Apply dynamic programming approach discussed in class. Provide a justification of your estimate.(ii) What are the minimal space resources you need for your computation, i.e. how many computed values do you need to keep in order to be able to compute aij?

In this project, you will create a class that can tell riddles like the following:- Riddle Question: Why did the chicken cross the playground?- Riddle Answer: To get to the other slide!1. First, brainstorm in pairs to do the Object-Oriented Design for a riddle asking program. What should we call this class? What data does it need to keep track of in instance variables? What is the data type for the instance variables? What methods do we need? (You could draw a Class Diagram for this class using Creately.com, although it is not required).2. Using the Person class above as a guide, write a Riddle class in the Active Code template below that has 2 instance variables for the riddles question and answer, a constructor that initializes the riddle, and 2 methods to ask the riddle and answer the riddle. Hint: Dont name your instance variables initQuestion and initAnswer well explain why shortly. If you came up with other instance variables and methods for this class, you can add those too! Dont forget to specify the private or public access modifiers. Use the outline in the Active Code below. You will learn how to write constructors and other methods in detail in the next lessons.3. Complete the main method to construct at least 2 Riddle objects and call their printQuestion() and printAnswer() methods to ask and answer the riddle. You can look up some good riddles online.4. public class Riddle{// write 2 instance variables for Riddle's question and answer: private type variableName;// constructorpublic Riddle(String initQuestion, String initAnswer){// set the instance variables to the init parameter variables}// Print riddle questionpublic void printQuestion(){// print out the riddle question with System.out.println}// Print riddle answerpublic void printAnswer(){// print out the riddle answer with System.out.println}// main method for testingpublic static void main(String[] args){// call the constructor to create 2 new Riddle objects// call their printQuestion() and printAnswer methods}}

7.4.4: Array iteration: Sum of excess.Array testGrades contains NUM_VALS test scores. Write a for loop that sets sumExtra to the total extra credit received. Full credit is 100, so anything over 100 is extra credit. Ex: If testGrades = {101, 83, 107, 90}, then sumExtra = 8, because 1 + 0 + 7 + 0 is 8.import java.util.Scanner;public class SumOfExcess {public static void main (String [] args) {Scanner scnr = new Scanner(System.in);final int NUM_VALS = 4;int[] testGrades = new int[NUM_VALS];int i;int sumExtra = -9999; // Assign sumExtra with 0 before your for loopfor (i = 0; i < testGrades.length; ++i) {testGrades[i] = scnr.nextInt();}/* Your solution goes here */System.out.println("sumExtra: " + sumExtra);}}

Design a linear-time algorithm which, given an undirected graph G and a particular edge e=(y,z) in it, determines whether G has a cycle containing e. Explain your algorithm/logic at a high-level in english. Pseudocode is optional but you must explain/state your algorithm at a high-level. Use the algorithms from class, such as DFS, Explore, connected components, as black boxes; but always make sure to specify the input for the algorithms.

t-Butly alcohol (TBA) is an important octane enhancer that is used to replace lead additives in gasoline. t-Butyl alcohol was produced by the liquid-phase hydration (W) of isobutene (I) over an Amberlyst-15 catalyst. The liquid is normally a multiphase mixture of hydrocarbon, water and solid catalysts. However, the use of cosolvents or excess TBA can achieve reasonable miscibility. The reaction mechanism is believed to be + I.S1 + W.S2. + . TBA.S + I.S3. TBA + S4Derive a rate law assuming:(a) The surface reaction is rate-limiting(b) The adsorption of isobutene is limiting

An MgO powder compact is prepared by dry pressing of an granulated powder with an average particle size of 0.5 m. The green density is 62% of theoretical. The compact is sintered in air at a temperature of 1500C to produce a ceramic that has a 99% theoretical density and an average final grain size of 2pm.(a) If the green compact has a diameter of 2 cm and a thickness of 1 mm, predict the fired geometry. (b) Predict how the following changes in the processing will affect the microstruc- ture and the porosity the polycrystalline ceramic; assume all other pro- cess steps are unchanged. (i) The powder has an average particle size of 3 m. (ii) The sintering temperature is reduced to 1300C.
