Given a training set of 50 million tuples with 25 attributes each taking 4 bytes space. One attribute is a class label with two distinct values, whereas for other attributes each has 30 distinct values. You have only a 1 GB main memory laptop. Outline an efficient method that constructs decision trees efficiently, and answer the following questions explicitly: Required:
a. How many scans of the database does your algorithm take if the maximal depth of decision tree derived is 5?
b. What is the maximum memory space your algorithm will use in your tree induction?

Assume you need to test a function named inorder. the function inorder receives three int arguments and returns true if and only if the arguments are in non-decreasing order: that is, the second argument is not < the first and the third is not < the second. write the definition of driver function testinorder whose job it is to determine whether inorder is correct. so testinorder returns true if inorder is correct and returns false otherwise. for the purposes of this exercise, assume inorder is an expensive function call, so call it as few times as possible!
