Write a subroutine in C# called analyzeHotspots that will count the number of hotspot symbols ('H') on a thermal sensor grid.

An example of the 2D array thermalGrid is shown in Figure 1.

Figure 1 Draw on this

The subroutine should:

• take the 2D array thermalGrid of characters as a parameter
• count the number of 'H' characters in the thermalGrid array
• output the warning CRITICAL OVERHEAT if there are eight or more 'H' symbols in the array
• output the total number of 'H' symbols if there are fewer than eight 'H' symbols in the array.

You must write your own count routine and not use any built-in search or count functions that might be available in C#.

You should use meaningful variable name(s) and C# syntax in your answer.
