In merge sort the whole is divided into two sub arrays. (This way of solving problem is called Divide and conquer algorithm) These sub arrays are called auxiliary arrays. First an array A is divided into two auxiliary arrays A1 and A2. Now these auxiliary arrays are further divided until we reach a stage with an auxiliary array of 2 elements. These 2 elements are arranged in incremental order and merged with the previous divided arrays. So we can say that auxiliary array is used to implement the basic principle of merge sort.

Why merge sort is not in-place?
this use auxiliar data structure for to work, in-place is that on the same data structure of input this sort
Difference between internal and external sorting?
Internal sorting it means we are arranging the number within the array only which is in computer primary memory. External sorting it is the sorting of numbers from the external file by reading it from secondary memory.
How do you sort a queue?
You don't. Queues are a first in, first out structure, specifically used to process incoming data in the same order it arrives. If you want to sort a data sequence then use an array or a list.
How many types of sorting array in C programming?
You can sort an array with any method you want, but there is a built-in qsort function, declared in stdlib.h (see the attached link).bubble sort, quick sort, insertion sort, merge sort, radix sort and lot more..merge sort is the most efficient one..
How do you sort an array of numbers?
Use a sorting algorithm. There are a bewildering number of sorting algorithms, both stable and unstable. To sort numbers, an unstable sort suffices. The algorithm you use will depend on how many numbers need to be sorted (a small or a large set), however a hybrid algorithm (a combination of two or more algorithms) can cater for both. Introsort (unstable) and timsort (stable) are the two most common hybrid sorting algorithms.
How do you merge and sort an array using PHP?
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 ?>
How would you sort a linked list?
Use merge sortUse tree sort
What is the difference between sort and asort in PHP?
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.
How do you write a program that accepts 50 integer values and sort them in basic programming?
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.

How do you merge arrays in PHP?
To merge arrays in PHP all you have to do is use the array_merge() function like shown below: <?php $array1 = array("Matt", "Michael", "Justin"); $array2 = array("Janice", "Janet", "Kylie"); $array3 = array_merge($array1, $array2); ?> One thing to remember when merging arrays is you might be creating duplicate results, if you don't want 2 or more of the same result in the array remember to use the function array_unique() to remove the duplicate results from it!
How do you sort variable in ascending or descending order both in php?
Assuming that the values are stored in an array, you can use the php function sort($array) to sort ascending, and rsort to sort descending. The following link gives a table that lists all of the built in PHP sort functions: http://php.net/manual/en/array.sorting.php
What is the Java program for sorting an array?
Java has a very efficient built in implementation of quick sort. You can use it on any array of primitives or Comparable Objects by invoking Arrays.sort(<array>) See related link.
