Using C#, write a subroutine to help a retail store review its daily sales performance.

The subroutine must:

• have the identifier CountHighSales
• take the number of days the store was open as an integer parameter
• prompt the user to enter the number of sales transactions completed on each of those days
• count how many of those days had more than 150 transactions
• return the completed count of those high-performance days.

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