the inner loop should be using the combinations structure in (n choose k)

baxy(nk) Consider the following programming segment. Your answer must rely on combinations structure. Answers that use sigma notation will not be accepted. counter =2000 for i=a+5 to 3n+1 do \{ counter = counter +7 for j=i+1 to 5n1 do \{ counter=counter+11 \} a) Determine the value that the variable counter has after the segment is executed. Provide your answer as a function of n (i.e. formula which depends on n ). Make sure to explain how/why the parts of the formula relate to counting. Explanation: Answer: b) Evaluate your answer in part a) for n=50 and a=10. Show the work Then check this number by implementing the code in programming language of your choice. Use the value n=50 and a=10 and print the variable counter after the code execution. You must provide the screenshots of implementation and output
