As a simple example, the numbers 1, 2, 3, 4, 5 are sorted in ascending order. In this tutorial, you will understand the working of selection sort with working code in C, C++, Java, and Python. If next element is grater than previous element just ignore it. Selection Sort is an algorithm that works by selecting the smallest element from the array and putting it at its correct position and then selecting the second smallest element and putting it at its correct position and so on (for ascending order). This “smaller than” relation is an ordered relation over the set from which the data is taken. Steps to Sort data First compare First (previous) element with its next elements. Ascending order: while sorting the data in ascending order, we try to arrange the data in a way such that each element is in some way “smaller than” its successor. The arrangement of data in a particular order is called as sorting of the data by that order. finding "Joe" in an attendance register of 100 students. These data arrangements give easier access to data for future use for ex. Another example is the attendance register at school/college which contains our names arranged in alphabetical order. For instance, during our school days, we are told to stand in the queue based on our heights. Often in real life, we are supposed to arrange data in a particular order. Sorting forms a great case study for those who want to learn Data Structures and Algorithms. Sorting of data is one of the most fundamental, yet important problem in computer science. Bubble sort is a simple sorting algorithm in which each element is compared with adjacent element and swapped if their position is incorrect.
