Insertion Sort for Singly Linked List – Searching and sorting – We have discussed Insertion Sort for arrays.In this article linked list is also discussed.
Find the Minimum length Unsorted Subarray, sorting which makes the complete array sorted -Searching and sorting – Given an unsorted array arr of size n. find the minimum length subarray arr[s..e]
Which sorting algorithm makes minimum number of memory writes – Searching and Sorting – Minimizing the number of writes is useful when making writes to some huge data set is very expensive, such as with EEPROMs or Flash memory, where each write reduces the lifespan of the memory.
stability in sorting algorithms – Searching and Sorting – Some sorting algorithms are stable by nature like Insertion sort, Merge Sort, Bubble Sort, etc. And some sorting algorithms are not, like Heap Sort, Quick Sort.
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).
Radix Sort – Searching and Sorting -The lower bound for Comparison based sorting algorithm (Merge Sort, Heap Sort, Quick-Sort .. etc is Ω(nLogn). i.e., they cannot do better than nLogn.
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.
