Problem 1 For each of the following three program fragments: A. Use big-O notation to analyze the running time (i.e. the value of sum). B. Implement the code in any programming language and give the actual running time for several values of N. o submit evidence you did this, i.e. the code you wrote C. Compare your analysis with the actual running times. o submit evidence you did this, i.e. tables or plots of data Fragment 1 sum = for i from 1 to n do sum = sum + 1 end Fragment 2 sum = 0 for i from 1 to n do for j from 1 to i do sum - sum + 1 end end Fragment 3 sum = 0 for i from 1 to n do for j from 1 to i^2 do for k from 1 toj do sum = sum + 1 end end end
