There are N lights above a road along the X-axis. The i-th light has Xi as its X-coordinate, and it is hung Yi above the road. The i-th light illuminates a triangular area, which is an isosceles triangle and its bottom edge is on the X-axis. The half of the top angle of the triangle is Zi degrees. (See the below figure) You have an aircraft which can fly on a fixed height. Because of some unknown reasons, this aircraft can fly only under the light. Your task is to find the maximum possible height for your flight from X=L to X=R. The lights do not block the aircraft, e.g., the aircraft can safely fly through a light. Develop a C++ program that solve the above problem, sample input output is listed below.

Write an expression that evaluates to True if the value assigned to X is even, but False if the value is odd.

Write a program that converts degree Kelvin(TK) to degrees Fahrenheit (TF)

A thermometer is removed from a room where the temperature is 70° F and is taken outside, where the air temperature is 10° F. After one-half minute the thermometer reads 57° F. What is the reading of the thermometer at t = 1 min? Assume that the rate of change of temperature in time is proportional to the difference between the thermometer's temperature and the air temperature. Type your answer in °F in the space provided below. Round your answer to two decimal places.
