The short answer Merge sort splits, sorts and merges, always in O(n log n), and it needs extra memory. Quick sort partitions around a pivot and sorts in place, averaging O(n log n) with an O(n squared) worst case. The…
The short answer B-Tree vs B+ Tree comes down to one structural choice: where record pointers live. Both are self-balancing, multi-way search trees built for disk storage. A node is sized to match one disk block, so a wide branching…
MLOps vs DevOps is the pivotal architectural question for every engineering organization adopting artificial intelligence in 2026 — and most teams are still trying to answer it by forcing machine learning workflows into pipelines designed for traditional software. The result…
The short answer A tree is a special, restricted kind of graph. A tree is connected and acyclic, and it has one root. For n nodes it always has exactly n−1 edges. So every node except the root has a…
In data structures, binary tree vs binary search tree serve different purposes. A binary tree is a hierarchical structure where each node has up to two children, while a binary search tree organizes data with a specific order to enable…
The short answer Both Prim’s and Kruskal’s are greedy algorithms that find the Minimum Spanning Tree of a weighted graph. Prim’s grows one tree from a start vertex, always adding the cheapest edge to a new vertex. Kruskal’s sorts all…
The short answer A linear data structure arranges elements in a single sequence, one after another, on a single level. Think of an array or linked list. A non-linear data structure arranges elements in a hierarchy or network, across multiple…
The short answer A stack works in LIFO order — Last In, First Out. You add and remove from the same end (the top), like a pile of plates. A queue works in FIFO order — First In, First Out.…
Clustered Index A clustered index defines the order in which data is physically stored in a table. The leaf nodes of a clustered index contain the data pages themselves. Advantages: Provides fast retrieval of rows based on the indexed column.…
