Study Notes
Floyd's Tortoise and Hare Algorithm
- Used for loop detection in linked lists
- Detects a loop by comparing node values
- Time complexity is O(n) for loop detection
Characteristics of Linked Lists
- A linked list with no loop has the last node pointing to NULL
- A linked list with a loop can be detected using Floyd's Tortoise and Hare algorithm
Bitonic DLL
- A Bitonic sequence is a sequence with both ascending and descending parts
- Typically sorted using the Bitonic Sort algorithm
- The merging step in the sorting process combines two sorted halves into a single sorted list
- Time complexity of sorting a Bitonic DLL using the Bitonic Sort algorithm is O(n log n)
Critical Step in Bitonic DLL
- Splitting the list into subproblems is critical for achieving the bitonic property
Segregating Even and Odd Nodes in a Linked List
- Efficient approach is iterative traversal
- Key idea is grouping nodes based on parity
- Maintaining the relative order of even and odd nodes during segregation is required for stability
- Achievable time complexity is O(n)
- Pointers are used to access neighboring nodes
Merge Sort for Doubly Linked List (DLL)
- Preferred choice for sorting a doubly linked list due to its ability to work well with linked lists
- Key step in the merge sort algorithm is merging sorted sublists
- Time complexity of the merge step is O(n log n)
- Merge sort maintains stability during sorting by maintaining the original order of equal elements
- Space complexity is O(n)
Minimum Stack
- Primary advantage is reduced space complexity compared to a regular stack
