One lap around a standard high-school running track is exactly 0.25 miles. Write a program that takes a number of miles as input, and outputs the number of laps. Output each floating-point value with two digits after the decimal point, which can be achieved as follows: System. out. printf("%.2f", yourValue); Ex: If the input is: 1.5 the output is: 6.00 Ex: If the input is: 2.2 the output is: 8.80 Your program must define and call a method: public static double milesToLaps(double userMiles)

Suppose there is a relation r(a, b, c) with a b+-tree index with search keys (a, b).1. what is the worst-case cost of finding records satisfying 10 < a < 50 using this index, in terms of the number of records n1, retrieved and the height h of the tree? 2. what is the worst-case cost of finding records satisfying 10 < a < 50 and 5 < b < 10 using this index, in terms of the number of records n2 that satisfy this selection, as well as n1 and h defined above? 3. under what conditions on n1 and n2, would the index be an efficient way of finding records satisfying the condition from part (2)?
