When counting the number of arithmetic operations in evaluating an expression, we often make the simplifying assumption that each operation has the same cost. For example, consider the following statement from the Merge-Sort algorithm for dividing the problem into two equal problems. q = ⌊(? + ?)/2⌋ we would say that the evaluation requires a total of 3 arithmetic operations (+, / and “floor”). That is, the time cost is 3. If that statement was embedded in a loop that...
