PYTHON Programming-Merge Sort for Doubly Linked List – Searching and Sorting – Merge sort for singly linked list is already discussed. The important change here is to modify the previous pointers also when merging two lists.
Why Quick Sort preferred for Arrays and Merge Sort for Linked Lists? – Searching and Sorting – Quick Sort in its general form is an in-place sort. whereas merge sort requires O(N) extra storage, N denoting the array size which may be quite expensive.
JAVA programming – Given a sorted array and a number x, find the pair in array whose sum is closest to x – Searching and sorting – Given a sorted array and a number x, find a pair in array whose sum is closest to x.
C++ programming – Given a sorted array and a number x, find the pair in array whose sum is closest to x – Searching and sorting – Given a sorted array and a number x, find a pair in array whose sum is closest to x.
C programming – Given a sorted array and a number x, find the pair in array whose sum is closest to x – Searching and sorting.- Given a sorted array. find a pair in array whose sum is closest to x.
Search in an almost sorted array – Searching and Sorting – A simple solution is linearly search given key in given array.Time complexity of solution is O(n).We cab modify binary search to do it in O(Logn) time.
QuickSort on Doubly Linked List – Searching and sorting -. The idea is simple, we first find out pointer to last node. Once we have pointer to last node, we can recursively sort the linked list using pointers to first and last nodes of linked list.
Sort a nearly sorted (K sorted) array – Searching and sorting – Given an array of n elements, where each element is at most k away from its target position.
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]
