Comb Sort – Searching and Sorting – Comb Sort is mainly an improvement over Bubble Sort. Bubble sort always compares adjacent values. So all inversions are removed one by one. Comb Sort improves on Bubble Sort by using gap of size more than 1.
ShellSort – Searching and Sorting – ShellSort is mainly a variation of Insertion Sort. In insertion sort, we move elements only one position ahead. When an element has to be moved far ahead, many movements are involved.
Bucket Sort – Searching and sorting – A simple way is to apply a comparison based sorting algorithm. The lower bound for Comparison based sorting algorithm (Merge Sort, Heap Sort, Quick-Sort .. etc) is Ω(n Log n), i.e., they cannot do better than nLogn.
Counting sort – Searching and Sorting – Counting Sort is a sorting technique based on keys between a specific range. It works by counting the number of objects having distinct key values (kind of hashing).
QuickSort – Searching and Sorting – Like Merge Sort, QuickSort is a Divide and Conquer algorithm. It picks an element as pivot and partitions.There are many different versions of quickSort that pick pivot in different ways.
Heap Sort – Searching and Sorting – Heap sort is a comparison based sorting technique based on Binary Heap data structure. It is similar to selection sort.where we first find the maximum element and place the maximum element at the end.
Prim’s MST for Adjacency List Representation – Greedy algorithm – We have discussed Prim’s algorithm and implementation for adjacency matrix representation. The time complexity for the matrix representation is O(V^2).
Merge Sort – searching and sorting algorithm – Like QuickSort, Merge Sort is a Divide and Conquer algorithm. It divides input array in two halves.
Prim’s Minimum Spanning Tree – Greedy Algorithm – We have discussed Kruskal’s algorithm for Minimum Spanning Tree. Like Kruskal’s algorithm, Prim’s algorithm is also a Greedy algorithm. It starts with an empty spanning tree the idea is to maintain two sets of vertices.
