JAVA Program Count 1’s in a sorted binary array – Searching and Sorting – A simple solution is to linearly traverse the array. The time complexity of the simple solution is O(n). We can use Binary Search to find count in O(Logn) time.
array sort
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]
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.
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.
Merge Sort – searching and sorting algorithm – Like QuickSort, Merge Sort is a Divide and Conquer algorithm. It divides input array in two halves.
