Q5) Consider the following programming segment ***You should note that the three for loops are nested loops. counter-0 fori-1 to n do \ for j i+1 to 2n do { counter- counter1 Your answer must rely on combinations structure. Answers that use sigma notation will not be accepted. a) Determine the value that the variable counter will have after the segment is executed. Provide your answer as a function of n (i.e. formula which depends on n). b) Test your formula by implementing this code in Java. Use the value n # 50 and print the variable counter after the code execution -then compare this value with the answer provided by your formula in part a). You must provide the screenshots of implementation and output
