Space complexity measures the amount of memory an algorithm uses as a function of the input size. Efficient algorithms minimize memory usage while maintaining acceptable performance.
Sorting is a common operation in computer science. Key sorting algorithms include:
- Quick Sort: Divides the array into smaller sub-arrays and recursively sorts them. Average time complexity is O(n log n).
- Merge Sort: Divides the array into two halves, recursively sorts them, and then merges the sorted halves. Time complexity is O(n log n).
- Heap Sort: Utilizes a binary heap to sort elements. Time complexity is O(n log n).
Searching Algorithms
Searching involves finding an element in a data structure. Key searching algorithms include:
- Binary Search: Efficiently searches sorted arrays by repeatedly dividing the search interval UAE Phone Numbers in half. Time complexity is O(log n).
- Hashing: Uses a hash function to map keys to indices in a hash table, allowing for average time complexity of O(1) for search operations.
Graph Algorithms
Graph algorithms solve problems related to networks. Key graph algorithms include:
- Depth-First Search (DFS): Explores as far as possible along each branch before backtracking. Used in applications such as topological sorting and detecting cycles.
- Breadth-First Search (BFS): Explores all nodes at the present depth level before moving Australia Phone Number on to nodes at the next depth level. Used in shortest path problems and level-order traversal.
- Dijkstra’s Algorithm: Finds the shortest path between nodes in a weighted graph. Time complexity is O(V^2) or O(E + V log V) with a priority queue.”Daa Structure and Algorithm Analysis in Python” is an invaluable resource for mastering the foundational concepts of computer science.
