Below are three approaches to solving the task. After showing the three approaches I list some advantages and disadvantages of each approach. Are there other advantages and disadvantages? Are there other approaches? I think we need some "terminology rectification" to approach this problem properly. Consider, for example, the following: Associated with Approach #1 is the statement: > 1. No computation needed. Simply search the list for the time of interest and then retrieve the distance and time values. Question: What is the difference between "computation" and "search"? Associated with Approach #2 is the statement: > 1. The values are not immediately available. Calculations are needed to reveal the values. Question: What is the difference between "computation" and "calculations"? Associated with Approach #3 are the statements: > 1. It is easy to get answers -- just specify a time and out pops the answers. No searching required as in Approach #1. No calculating as in Approach #2. and > 1. It requires an engine to execute or interpret the code. If a user is at a location with just pencil and paper then code isn't helpful. Questions: 1. What is the difference between "execution", "interpretation", "computation", "calculation", and "search"? 2. If Approach #3 "requires an engine to interpret or execute the code", are you saying that Approaches 1 and 2 require no such engine? Or, to put it another way, what is it in Approaches 1 and 2 that does "searches" and/or "calculations"? --Frank
