Study Notes
Recursive Algorithms
- Factorial algorithm has a time complexity of O(n)
- Fibonacci Sequence algorithm has a time complexity of O(2^n)
- Tower of Hanoi algorithm has a time complexity of O(2^n)
Searching Algorithms
- LRSearch (Left-to-Right) Algorithm: examines elements from the left side of the list until a match is found or the end of the list is reached
- Best case: O(1)
- Worst and average cases: O(n)
- RLSearch (Right-to-Left) Algorithm: examines elements from the right side of the list until a match is found or the beginning of the list is reached
- Best case: O(1)
- Worst and average cases: O(n)
- Binary Search Algorithm: divides the sorted list in half repeatedly, discarding half of the remaining elements based on the comparison with the target value
- Best case: O(1)
- Worst and average cases: O(log n)
- Linear Search Algorithm: sequentially checks each element in the list until a match is found or the entire list is traversed
- Best case: O(1)
- Worst and average cases: O(n)
Sorting Algorithms
- Merge Sort: divides the array into two halves, recursively sorts each half, and then merges the two sorted arrays
- Time complexity: O(n log n)
- Stable and suitable for large datasets
- Selection Sort: divides the array into a sorted and an unsorted region, and selects the smallest element from the unsorted region to swap with the first element of the unsorted region
- Time complexity: O(n^2)
- Simple, but performs poorly on large datasets
- Bubble Sort: repeatedly steps through the list, compares adjacent elements, and swaps them if they are in the wrong order
- Time complexity: O(log n) for pre-sorted datasets
- Efficient for sorted lists, but requires a pre-sorted dataset
- Insertion Sort: builds the sorted array one element at a time by repeatedly taking elements from the unsorted part and inserting them into their correct position in the sorted part
- Time complexity: O(n^2)
- Simple, efficient for small datasets or partially sorted data
