Given you have been making such videos for sometime. I would love to know how have you perfected the art of this? Meaning you might have created a process for this which makes your creation of such videos fast. Would you share your recipes with us?

Most arrays are small. A linear scan is fine for small arrays. Larger amounts of data are typically stored in databases which do not used arrays (generally) and are generally based on B-tree as mentioned in the video. B-tree is quite different from binary trees in concept.

@no-tomorrow7425 7 ай бұрын

Yeah, I agree with this point. For large amounts of data one usually just uses the search functionality offered by databases... no need to implement search from scratch (unless one works for a database company :) )

"B-tree is quite different from binary trees in concept." What do you mean? Is a binary tree not simply a B-tree where the minimum and maximum number of child nodes are 0 and 2 respectively? Yes, binary trees are often balanced, but they don't strictly have to be, and B-trees are usually balanced too, though in a slightly different manner.

Unlike b- or binary trees a sorted array has zero (pointer) overhead, so it’s great when it can be pre-calculated and is static.

@angeldude101 7 ай бұрын

A binary search splits the remaining nodes into two at each node. Similarly, you can make a "ternary search", where you check 2 roughly evenly spaced nodes to determine which of 3 sectioning the desired node is in. A B-tree is ultimately a "variable-ary search tree", where the number of immediate children of a given node isn't a fixed 2 or 3, but can vary depending on the situation, such as based on how many nodes will fit within a pre-decided maximum size when the nodes themselves might not necessarily have a constant size (though they should be the same within a given node to enable random access). Often, finding which child node has a desired value is done with a linear search of the values in the current node.

@dr_regularlove 7 ай бұрын

@@angeldude101 Thanks for that, yeah I can see how this would lend itself well to use cases such as DB indexing, especially with tunable parameters like that pre-decided maximum size with variably sized nodes like you mentioned. Still would love to see a Dreams of Code style video going into it with the minimalist visual aids that imo can go a long way in terms of really impressing a concept into the brain.

Note that CPUs with cache lines and prefetching (like x86), linear search until a couple of MB is the fastest you can get. It is easy to do the benchmarks yourself.

@angeldude101 7 ай бұрын

One of the reasons to prefer linear search over binary search is the cache, since reading one value will make the CPU implicitly fetch the values around it, and if you can use those rather than discarding all of them and jumping away, then the fewer data transfers can actually trump the fewer operations of the binary search. However it is actually possible to get the best of both worlds, with fewer comparisons while still respecting the cache. It just requires an unusual form of sorting. The structure is similar to an array-backed heap, but the order of the nodes is that of a traditional binary search tree. This type of structure was first described by Michaël Eytzinger in 1590 for efficiently searching through genealogical data and a person's ancestry... on paper.
