Problem 2

When searching a sorted array sequentially, you can ascertain that a given item does not appear in the array without searching the entire array. For example, if you search the array 2 5 7 9 for 6, you can use the approach described in Segment 18.8. That is, you compare 6 to 2, then to 5, and finally to 7. Since you did not find 6 after comparing it to 7, you do not have to look further, because the other entries in the array are greater than 7 and therefore cannot equal 6. Thus, you do not simply ask whether 6 equals an array entry, you also ask whether it is greater than the entry. Since 6 is greater than 2, you continue the search. Likewise for 5. Since 6 is less than 7, you have passed the point in the array where 6 would have had to occur, so 6 is not in the array. a. Write an iterative method contains to take advantage of these observations when searching a sorted array sequentially. b. Write a recursive method search that a method contains can call to take advantage of these observations when searching a sorted array sequentially
