Determine Day Type

You are given 24 temperature measurements recorded hourly over the course of a day. Your task is to determine whether the day is a Hot Day or a Cool Day.

First, compute the average temperature using the formula:

\(\text{average} = \frac{\sum_{i=1}^{24} t_i}{24}\)

If the average temperature is strictly greater than 30, output "Hot Day"; otherwise, output "Cool Day".

If the input does not consist of exactly 24 temperature values, output "Invalid input".

inputFormat

The input is provided via standard input (stdin) as a single line of space-separated floating-point numbers. There should be exactly 24 numbers representing the temperature measurements for each hour.

outputFormat

The output should be printed to standard output (stdout) as a single line. Output "Hot Day" if the average temperature is strictly greater than 30, otherwise output "Cool Day". In the case of an invalid number of inputs, output "Invalid input".## sample
