In this algorithm, lets say we start with node x, then we will visit neighbours of x, then neighbours of neighbours of x and so on. Algorithm To traverse a graph using BFS, we use queue to store the nodes and array data structure to distinguish the unvisited nodes. 1. Create empty ...
Dijkstra's algorithm solves the single-source shortest-paths problem in edge-weighted digraphs with nonnegative weights using extra space proportional to V and time proportional to E log V (in the worst case). 2. BFS Find shortest path 2.1 1091.Shortest Path in Binary MatrixLoading... Given ...
The product of any prefix or suffix of nums is guaranteed to fit in a 32-bit integer. You must write an algorithm that runs in O(n) time & without using the division operation. 🐣: Input: nums = [1,2,3,4], Output: [24,12,8,6] 🐢 Solution: 🔨 Brute Force ⏰: O(N^...

An alternative algorithm called Breath-First search provides us with the ability to return the same results as DFS but with the added guarantee to return the shortest-path first. This algorithm is a little more tricky to implement in a recursive manner instead using the queue data-structure, as...
