Program Plan Intro
Binary search:
- Binary search is a smart search process that searches for the particular element that is present in the array from the middle towards the left or right until the search element is found.
- The search element is searched from the middle as the elements present in the array needs to present in the sorted order.
- If the search element is larger it will search towards the right of the array.
- If the search element is smaller it will search towards the left of the array.
- The search continues in a narrow way that it searches for the quarter of the array until there are no values left in the array to search or compare.
- The search of the target element is made in the smart way it eliminates a portion of array based on the given element as the array is sorted.

If an has n elements, then the first value in the array can always be accessed with a[1]. What is true, and what is false?
Data Structure & Algorithm:
Here is an array with exactly 15 elements:1 2 3 4 5 6 7 8 9 10 11 12 13 14 15Suppose that we are doing a serial search for an element. Circle any elements that will be found by examining two or fewer numbers from the array.
If N represents the number of elements in a list, then searching for an element in a
sorted array-based list takes no less than O(N) time.
