Question

The following algorithm adds all the entries in the “upper triangular” part of a square n × n array A. Analyze this algorithm where the work unit is the addition operation, sum = sum + A[k, j]. In terms of n, how frequently is the sum operation done? Pick the smallest value below that must be done in order to sum the entries.

sum = 0

for k = 1 to n do

for j = k to n do

sum = sum + A[k, j]

end for

end for
