Consider the problem to compute the sum of the upper triangular matrix an nxn matrix A. Below is the pseudocode of the algorithm to compute this sum SumUpperTriangularMatrix (A) 1: S = 0 2: for j = 1 ton 3: for i = 1 toj 3: // Add 4: S = S + A[i][j] 5: return S All the questions in this exercise are related to the SumUpper TriangularMatrix(A) algorithm. The objective of this exercise is to explore whether the time complexity will change if we count different "actions. In this case, we count the number of comparisons performed by the "for loops (Lines 2 and 3). Answer the following questions to determine the total number of comparisons performed by the algorithm SumUpper TriangularMatrix(A). a. How many comparisons are performed by the "for loop in Line 2? b. Let us call t the number of comparisons performed by "for loop" in Line 3 for a given value of j. Fill in this table (Justify how you find tj only for j= 1 and j=n): j tj 1 2 3 j n c. Express the total number of comparisons performed by the "for loop in Line 3 during the execution of SumUpper TriangularMatrix(A). d. Express the function fe(n) that represents the overall total number of comparisons performed by the for loops in Lines 2 and 3 during the execution of SumUpper TriangularMatrix(A). e. The function f(n) grows like which function
