Array An array is used to group related data items of the same type into an ordered collection under a single name. Any particular element in the array can be indexed (referenced) by its numeric order within the dimension(s) of the array. As an example, the GPAs of all students in a section could be stored in the array variable Section_GPAs.

The array can only be divided in half down to size 1 lg n times, and each time 1 compare is done. 1 * lg n = lg n 1.3-6 Observe that the while loop of lines 5 – 7 of the Insertion-Sort procedure in Section 1.1 uses a linear search to scan (backward) through the sorted subarray

1) The value we are searching for is in the array. 2) Each value is equally likely to be in the array. 3) The size of the array is n = 2k-1, where k is a positive integer. The first assumption isn't necessary, but makes life easier so we don't have to assign a probability to how often a search fails.

Problem 6: Linear Search. It is often important to search for a value in an array. If the array is not sorted, then the only way to search is to examine each array cell one-by-one. This technique is called linear search. Define a function: public static int linearSearch(int[] data, int key) The precise specification of this function is as follows.

Search the array of readings for a specific reading. Sort the reading in ascending or descending order. (a) Print Reading. This exercise requires a traversal of the array for all of the data values. The array index ranges from 0 to rainfall.length - 1 (11) inclusive. Since there are four quarters in the year we must divide the index range by three.

One of the most common tasks performed on an array is a search for a particular value. Let’s look at a straightforward way to do this in a segment of code. Assume the array numbers is already filled with values and that all of the variables used have already been defined appropriately.

You have to search the array 100 times to determine if a given element is present or not. What will result in less work? Sorting the array with quicksort and then doing the searches using binary search OR just doing the searches with linear search. (without sorting) Justify your answer with calculations.

The Binary Search. The linear search algorithm we recently studied is easy to understand, but not very efficient: On the average, a linear search of “N” elements will examine N/2 elements before finding a value that is stored in the array. A linear search must examine all N elements to determine that the key is not in the array.
