Because in any type of search the element can be found at the last position of your array so time complexity of the program is increased..so if array when sorted easily finds the element within less time complexity than before..
You would sort the given elements of an array by a bubble sort or heap sort code!!
The minimum number of swaps required to sort an array is equal to the number of inversions in the array.
When you want to sort an array.
To merge and sort an array in PHP you need to use the array_merge() and sort() functions like shown in the example below: <?php $array1 = array(1, 5, 3, 9, 7); $array2 = array(8, 2, 6, 4, 0); // merge the arrays $merge = array_merge($array1, $array2); // 1, 5, 3, 9, 7, 8, 2, 6, 4, 0 // sort the array sort($merge); // 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 ?>
The bubble sort algorithm can be applied to an array of characters. Every character can be translated to an integer equivalent via the ascii table
sort() will order the array by its values without preserving the keys. Use it when array is indexed numerically or when you do not care about the keys. asort() will also sort the array by its values, but it will preserve the key -> value association.
Sorting an array.
Sort the array then traverse the array, printing the element values as you go.
Using sorted(array,reverse=True)
Create an array with 50 elements and input the integers one a time, filling the array. Use an insertion sort on the array for each input except the first. Alternatively, input the values first and then use insertion sort.
The simplest would be to put the numbers into an int[] (integer array) and pass that to java.util.Arrays.sort(int[]) (a static method), which will sort the array in ascending numerical order. Use a float[] or double[] if you need to sort non-whole numbers. You can also use the Collections.sort(List) method to sort the List directly. Or the Collections.sort(List, Comparator) if you wish to specify your own sorting criteria.
In order to determine which of four number is bigger you need 16 if statements arranged in a nested if statement. That exceeds the complexity of just sorting it in an array. Here is a solution using a simple array sort. int array[] = {7, 2, 27, 4}; int i, swap; do { swap = 0; for (i = 0; i < 4; ++i) { if (array[i]<array[i+1]) { swap=array[i]; array[i]=array[i+1]; array[i+1]=swap; swap=1; } } } while (swap == 1); printf ("%d\n", array[0]);
