Using C#, write a subroutine to help a meteorological station analyse precipitation patterns.

The subroutine must:

• have the identifier CountHeavyRainDays
• take the number of days in the monitoring period as an integer parameter
• prompt the user to enter the rainfall (in mm) recorded on each of those days as an integer
• count how many of those days had strictly more than 45 mm of rainfall
• return the completed count of these heavy rainfall days.

You should use meaningful variable names and correct C# syntax in your answer.
