Given an array n integers, find and print all the unique triplets (a, b, c) in the array which give the sum K. (a+b+c=K).Input

The first line of the input will be space separated integers, denoting the elements of the array. The second line of the input will be an integer denoting the required sum KOutput

The output should be multiple lines, each line containing a unique triplet. The elements of the triple must be sorted in increasing order and all the triplets printed must be sorted in increasing order. Print "No Matching Triplets Found" if there are no triplets with the given sum.Explanation

When the given array is [0, 1, 2, 3, 5, 7, 13, 17, 19, 19] and the required sum is 22, the triplets (0, 3, 19), (0, 5, 17), (1, 2, 19), (2, 3, 17) and (2, 7, 13) have the given sum 22.

Consider the following structure used to keep record of a module: struct Module { string moduleName; string moduleCode; string lecturer; int nrStudents; } Turn the Module struct into a class. The class should have member variables for all the values in the corresponding struct. Make all the member variables private. Include public member functions for each of the following: a default constructor that sets the string member variables to blank strings, and the int member variable to 0 overloaded constructor that sets the member variables to specified values;  member functions to set each of the member variables to a value given as an argument to the function member functions to retrieve the data from each of the member variables Test the class in a program that instantiates an object of class Module. The program should then input values for the object and use the mutators to assign values to the member variables. Use the accessors to obtain the values

Write down the R solutions of the following question.

Use the following data to construct a confidence interval for the true mean difference between scores of two independant groups. Use a 95% level of confidence. Group1: 65, 58, 78, 60, 68, 69, 66, 70, 53, 71, 63, 63

Group 2: 62, 53, 36, 34, 56, 50, 42, 57, 46, 68, 48, 42, 52, 53, 43 

Write down the R solutions of the following questions.

A shoe company wants to compare two materials, A and B, for use on the soles of boys' shoes. In this example, each of 10 boys in a study wore a special pair of shoes with the sole of one shoe made from Material A and the sole on the other shoe made from Material B. The sole types were randomly assigned to account for systematic differences in wear between the left and right foot. After three months, the shoes are measured for wear. The results are: Material A = 13.2, 8.2, 10.9, 14.3, 10.7, 6.6, 9.5, 10.8, 8.8, 13.3 Material B = 14, 8.8, 11.2, 14.2, 11.8, 6.4, 9.8, 11.3, 9.3, 13.6

Test the hypothesis H0: µdifference = 0 versus H1: µdifference≠ 0 at 95% confidence level.
