It has less space complexity, it requires a single addition to memory space.It is important for smaller data sets, but inefficient for large data sets.Step 1: There is no element on the left side of 7 so leave the element as it is. Repeat all the steps until the list is sorted.Shift all the elements in the sorted sublist that are greater than the elements to be sorted.Now compare with all the elements in the sorted sub-list.Leave the first element of the list, move to the next element in the array.Steps will be repeated until all the elements are not sortedįollowing image is showing the selection sort in a better way:.Now that leftmost element will be the part of the sorted array and will not be included in the unsorted array in the next iteration.Iterate that sorted element with the leftmost element in the unsorted list.When we reach the end we will get to know the sorted element in the list.The first step is to iterate the complete array.It generally follows the approach of selecting the smallest element from an unsorted array and that smallest element is placed at the leftmost which becomes the part of sorted array finally. Initially, the sorted array is an empty array and an unsorted array has all the elements. Two arrays are maintained in case of selection sort: It is an in-place comparison-based sorting algorithm. Selection Sort: Selection sort repeatedly finds the minimum element from an unsorted array and puts it at the beginning of the array. Hence, for a large set of data, this sorting algorithm is not useful. The Disadvantage of using bubble sort is that it is quite slow.įor Example: Consider an unordered list.
Let’s explain them with the help of examples:īubble Sort: In bubble sort, if the adjacent elements are in the wrong order, they are swapped continuously Sorting may be classified into different types.Some major sorting algorithms are: Gathering for morning prayers and get arranged in the ascending order of height.Arranging clothes on the basis of new to old.Arranging the books on the basis of chronology.
