2. Javascript is an example of a high-level programming language, as are other languages such as Java, C++, and PHP. Describe two (2) advantages that high-level languages have over low-level machine languages. In particular, mention how high-level languages make it possible to develop software in a more natural, convenient manner. (5 points) 3. When searching for an item in a sorted list (e.g., a phone book), the binary search algorithm is extremely efficient. Binary search checks the entry at the middle of the list and, depending on whether that entry comes before or after the desired item, repeats the search on the left or right half of the list. (IO points) a. What is the best case for searching the list? That is, where would the item need to be in the list in order to require the minimum number of checks to find it? Explain your answer. b. What is the worst case for searching the list? That is, where would the item need to be in the list in order to require the maximum number of checks to find it? Explain your answer.
