Key algorithms every developer should know

Algorithms are fundamental methods for optimizing and solving computational problems. Here are several key algorithms every developer should know.

1. Breadth-First Search (BFS)

BFS is used to explore nodes of a graph or tree, level by level. It’s ideal for finding the shortest path in an unweighted graph. BFS uses a queue to manage traversal.

2. Depth-First Search (DFS)

DFS dives deep into each branch before backtracking. It's great for exploring all nodes or solving problems like detecting cycles in a graph. DFS can be implemented using recursion or a stack.

3. Quick Sort

Quick Sort is an efficient sorting algorithm that uses the divide-and-conquer approach. It selects a 'pivot' element and partitions the array around it. It has an average time complexity of O(n log n).

4. Dijkstra's Algorithm

Dijkstra's Algorithm finds the shortest paths from a source to all nodes in a graph with non-negative weights. It uses a priority queue to efficiently select the next node to process.

For practice, interactive platforms like LeetCode are perfect. They offer a wide range of problems to strengthen your understanding of these algorithms.
