Question
The minimum number of arithmetic operations required to evaluate the polynomial for a given value of , using only one temporary variable is ______.
Correct answer
7 to 7
Solution
We can rewrite the polynomial to minimize operations:Using one temporary variable and input :
1. (Computes ) [1 mult]
2. (Computes ) [1 add]
3. (Computes ) [1 mult]
4. (Computes ) [1 add]
5. (Computes ) [1 mult]
6. (Computes Result) [1 add]
Total arithmetic operations = 3 multiplications + 3 additions = 6.Continue learning with Success Tracker
