Cluter Write a program to implement the k-means algorithm.• The input of the program should is a set of 150 observations of iris data.• Each observation contains petal length, petal width, sepal length, sepal width and the type of irisRequirements• The program should be run your with k=3• The output should be in a chart with rows and columns. It should give a number of each species ofiris in each cluster.

Bus timetables specify to the second the exact arrival and departure time of each bus on each stop. You need to pay for the full fare of every bus you ride and different bus lines charge different fees , but they are flat fees (independent of distance travelled on the line) A travel plan is a sequence of stop-time pairs where stop is a location of a bus stop and time is when we arrive at that stop. The plan is feasible if for any two consecutive pairs (a, t) and (b, t′) in the plan there exists a bus that departs after t and arrives at b at exactly t′. That is, a travel plan does not allow us to walk between stops. Assuming that no two buses arrive at the same time at the same stop, a feasible plan uniquely identifies the bus lines that we need to take to realize the plan. The cost of the plan is the sum of the fares we need to pay. Your task is to design an efficient algorithm that given a departure time t, an arrival time t′, an origin stop a and a destination stop b, finds the…

(Numerical) Write a program that tests the effectiveness of the rand() library function. Start by initializing 10 counters to 0, and then generate a large number of pseudorandom integers between 0 and 9. Each time a 0 occurs, increment the variable you have designated as the zero counter; when a 1 occurs, increment the counter variable that’s keeping count of the 1s that occur; and so on. Finally, display the number of 0s, 1s, 2s, and so on that occurred and the percentage of the time they occurred.

Review Loops Write a java program to ask three people three questions about name, number of courses, and number of credit hours. Also, print result in columns as below. Note:  the input.nextInt() method reads only the integer value from input buffer.The "\n" is still staying in the input buffer.  If you continue reading with input.nextLine(),you will receive the "\n" and CPU will not wait for any input. To fix this problem, you addthe statement input.nextLine() to flush out the "\n" from the input buffer.
