Study Notes
Merge Sort vs Selection Sort
- Merge sort has a faster time complexity than selection sort, making it a more efficient sorting algorithm.
Recursion Scenarios
- Recursion is more useful when dealing with problems that have a recursive structure, such as tree or graph traversals.
Merge Sort Fundamentals
- The fundamental idea behind merge sort is to divide the list into smaller sublists, sort each sublist, and then merge the sorted sublists into a single sorted list.
Merging Sorted Lists
- The key step in merging two sorted lists is to compare the smallest elements from each list and add the smaller one to the resulting sorted list.
Iterative Merge Sort
- Merge sort is considered messy to write iteratively because it requires a stack data structure to mimic the recursive function calls, making the implementation more complex.
Recursion Applications
- The most common application of recursion is in tree or graph traversals, where the recursive function calls can be used to navigate the recursive structure of the data.
Recursive Behavior
- The simple base case in recursive behavior refers to the trivial case that can be solved directly, without the need for further recursion.
- A process that exhibits recursion is called a recursive function.
- A recursive step in a recursive behavior does the same task that the function does, but with a smaller input, eventually leading to the base case.
Recursion in Disciplines
- Recursion is used in various disciplines, including computer science, mathematics, and biology, to solve problems that have a recursive structure.
