Imagine that you work for a database company, which has a popular system formaintaining sorted sets. After a negative review in an influential technology website,the company has decided it needs to convert all of its indexing software fromusing sorted arrays to an indexing strategy based on using binary search trees, soas to be able to support insertions and deletions more efficiently. Your job is towrite a program that can take a sorted array, A, of n elements, and construct abinary search tree, T, storing these same elements, so that doing a binary searchfor any element in T will run in O(log n) time. Describe an O(n)-time algorithmfor doing this conversion

Mixture Models and Digit Classification 3 points possible(graded) Assume that we have 100.000 black-and-white images of size 26 X 26 pixels that are the result of scans of hand-written digits between 0and 9. We can apply mixture models to effectively train a classifier based on clustering using the EM algorithm applied to the dataset. Identify the following parameters (according to notation developed in the lecture,assuming that we use all the data for training): K= 2 d= Submit You have used 0 of 2 attempts Save Note The Gaussian mixture model can be extended to the case where each mixture component has a general covariance matrix , The case that we have studied so far is a special case where = I, where I is the identity matrix of size d X d.The EM algorithm can also be extended to work in this general setting.

You developed a serial algorithm to combine N integers stored in an array, X, into a singleinteger: y.y = X[0];for(i = 1; i < N; i++){y = y + X[i] + y*X[i];}The operation, = + + , is invoked in every iteration. As you can see, thisoperation is commutative and associative. This means that you may apply this operationrecursively to pairs of numbers in a list in any order and still obtain the correct result.Now you need to accelerate this serial algorithm by off-loading most of its computation to GPU.The remaining computation can be finished off in the CPU. Please implement the kernelfunction below. Create any variable that you need to use in the kernel function or assume thatthey have been created elsewhere for you. Please pay attention to properly handling theboundary conditions in the kernel function

Then create a new Java application called "RecursiveTriangle" (without the quotation marks) according to the following guidelines.Modify the example in Horstmann Section 5.9, pp. 228-230 so that the triangle displays "in reverse order" as in the example below, which allows the user to set the number of lines to print and the String used for printing the triangle.Use a method to prompt the user for the number of lines (between 1 and 10) to print. This method should take no parameters and return an int value.Use a method to prompt the user for the string to be used when printing the pattern. This method should take no parameters and return a String value.Use a method called printTriangle that takes an int and a String as parameters (i.e., the return values from the two methods mentioned above) and has no return value. That method should use recursion to print the "reversed triangle" as in the following example.EXAMPLE: The call to printTriangle(numLines, pattern) should print the following, assuming numLines has the value 4 and pattern has the value "[]".[][][][][][][][][][]MUST BE IN JAVA
