I have been having problems with this question for a bit. Its for my assembly language class and would like some assistance. Can you please show work so I know how you got your answer (3 points) The rules for naming valid identifiers in a certain programming language are as follows: Only alphabetic characters ('A' through 'Z' and 'a' through 'z'), digits ('0' through '9') and underscore ('_') are permitted. Cannot begin with a digit ('0' through '9'). (Must begin with an alphabetic character or underscore.) Case sensitive. Cannot match any reserved keyword. How many distinct and valid six-character long identifiers can be formed following the above rules, assuming none of the reserved keywords is six-character long?

CAUTION:

You will earn NO CREDITS if you don't clearly show working (i.e., how you arrive at the required quant
