Write Java program that asks the user to enter an integer number than accomplish each of the following tasks: a) If the number is equal to 7, display "The variable number is equal to 7". b) If the number is not equal to 7, display "The variable number is not equal to 7". You have to resolve the exercise using if statement only.

4.You can also answer the third question using the mathematical method. That is, both d&c and DP are interpreted as Recurrence Relations (Equations). The difference between Linear Recurrence and Divide & Conquer The difference between Divide & Conquer and DP is explained mathematically in terms of the difference between Linear Recurrence and Divide & Conquer.

Mention some drawbacks of the Linear Model?

Kevin plans to employ a Boolean operator as he is inclined towards investigating two discrete fields of study. It is imperative for Kevin to utilise the appropriate Boolean operator during the process of conducting a search in order to obtain dependable outcomes.

Marco Dorigo developed Ant Colony Optimization (ACO) algorithm and this algorithm is used to solve many case studies. Let's say, you are using ACO to solve Travelling Repairman Problem (TRP). Describe the process on how ACO implemented in TRP case study. State if there are any improvisation you would like to make in ACO to improve the implementation in TRP case study. Following Figure 2 shows the definition of the case study. Also, include which algorithm, PSO or ACO, is better used for solving TRP case study. You may use any illustration/description to describe your solution. Travelling repairman problem (TRP) is a scheduling problem whereby a repairman must visit the scheduled locations to conduct the job needed. Each location has a period/time in which the repairman is allowed to arrive. This is to allow maximum number of repair jobs are successfully performed.

Q.1: a. What is TFIDF? What is significance of IDF? Explain role of IDF in classification with one real life example. Give an example where IDF may not make sense while classifying. b. Explain how can you apply TFIDF to classify product reviews? (Here each post has 20 words). Give Pseudo code for the same. c. Discuss an algorithm to rank these reviews for different new customers based on their personalized parameters. (Make necessary assumptions) d. Can you combine CNN and TFIDF in this case? How? e. Discuss an algorithm where you combine different reviews to provide a single personalized review of the product for a particular customer.

How does that solve the above question?
