This is a king divide and conquer technique. How Binary Search Algorithm Works? It is important that the Elements entered in the Array must be in the Sorted Order otherwise the Binary Searching Algorithm would not work as expected. The search for the element starts by comparing the middle element first.
The elements must have a total order and the index of the array can be of any discrete type. For languages where this is not possible, sort an array of integers.
The bubble sort is generally considered to be the simplest sorting algorithm. Because of its simplicity and ease of visualization, it is often taught in introductory computer science courses. Because of its abysmal O n2 performance, it is not used often for large or even medium-sized datasets.
The bubble sort works by passing sequentially over a list, comparing each value to the one immediately after it.
If the first value is greater than the second, their positions are switched. Over a number of passes, at most equal to the number of elements in the list, all of the values drift into their correct positions large values "bubble" rapidly toward the end, pushing others down around them.
Because each pass finds the maximum item and puts it at the end, the portion of the list to be sorted can be reduced at each pass. A boolean variable is used to track whether any changes have been made in the current pass; when a pass completes without changing anything, the algorithm exits.
This can be expressed in pseudo-code as follows assuming 1-based indexing:Selection sort algorithm starts by compairing first two elements of an array and swapping if necessary, i.e., if you want to sort the elements of array in ascending order and if the first element is greater than second then, you need to swap the elements but, if the first element is smaller than second, leave the elements as it is.
Cachegrind simulates how your program interacts with a machine's cache hierarchy and (optionally) branch predictor.
It simulates a machine with independent first-level instruction and data caches (I1 and D1), backed by a unified second-level cache (L2). To sort an array in ascending order using selection sort technique in C++ programming, then you have to ask to the user to enter the array size and array elements, now start comparing the array elements and start placing the smaller elements before bigger to arrange all the array elements in ascending order.

This external version of the ABAP key word documentation only supports text . did your selectionSort function work for integers?. If it did not work for integers then I would recommend you to fix that before moving on to String version – arunmoezhi Apr 28 '14 at string has comparison methods and overloaded operators.
