25 matches found for 'search'

... example, \([0,1,2,4,5,6,7]\) might become \([4,5,6,7,0,1,2]\). You are given a target value to **search**. If found in the array return its index, otherwise return \(-1\).
Note: You may assume no duplicate exists in the array.

Preface
Elastic**search** is a distributed, open source **search** and analytics engine for all types of data, including textual, numerical, geospatial, structured, and unstructured.

Context
Depth-first **search** (DFS) is a common **search**ing algorithm for graphs, alongside Breadth-first **search** (BFS).
DFS is useful for finding ways to solve mazes.

... Service
Text autocomplete is so popular that a solution was made specifically for it - **search** engines. These include well-known names like Elastic**search** and Solr, which are powered by Lucene under the hood.

... others.
What is an index?
An index at the most basic level has at least two columns:
A **search** key column that this index is based on
The pointer column to the actual location of the row in another table
In most RDBMS implementations, you are allowed to create an index based off of a column.

... among all the database servers. However, one problem with this approach is that if we need to **search** for a range of tweets, then we would have to query all of the servers, collate them, and sort them (assuming that we want to **search** by creation date) before we give them back to the client.

There are a few ways to **search** for a string in Python (3+):
String operations
str.find(sub[, start[, end]])]
"shadow walker".find('w') => 5
This gives you the index of the first match.

... a trie (pronounced "try"), also called digital tree, radix tree or prefix tree, is a kind of **search** tree—an ordered tree data structure used to store a dynamic set or associative array where the keys are usually strings.

... at another lambda function that deals with A.I. heuristics.
Material: http://ai.berkeley.edu/**search**.html
h = lambda x: heuristic(x[0], problem)
heuristic is a function that takes in a node, and the **search** problem.

... found that every 100ms of latency cost them 1% in sales. Google found an extra .5 seconds in **search** page generation time dropped traffic by 20%. A broker could lose $4 million in revenues per millisecond if their electronic trading platform is 5 milliseconds behind the competition.

... \(3\). At \(i = 3\), \(A[i] = 1\), so replace with this value with the former \(3\) and then **search** for index \(1\) now. At \(i = 1\), \(A[i] = 1\), which is a duplicate since \(i = A[i]\), so we return \(i\).

... NP set, because P problems can also check their solutions efficiently (on top of being able to **search** for a solution efficiently).

... function and is normally a hand-coded function. For example, the A* algorithm uses heuristics for **search**ing. At its core, it is a helper function.
In a ML context, it is not based on a model obtained by training on a data set, but typically embodies some common-sense expertise from domain experts.

Cheat Engine (CE) is an open source memory scanner/hex editor/debugger that works for Windows applications. Another way to put it is that CE is used to explore the memory that is dynamically allocated (by Windows) in games.

Tries
Pronounced "try-es"
Faster alternative to string **search**ing, but can be space heavy.
Basically a tree of nodes with R pointers (hence a R-tree), where R is the number of distinct characters that can be used (Radix).

... as the entry color), and these points may be color-grouped in big lumps.
It is much better to **search** the points closest to the entry point first. This makes BFS an excellent choice.

... studying. Core concepts will always trump niche knowledge such as Math tricks with pow/modulo or **search**ing substrings using Rabin-Karp. Things like bitwise operators and multi-threading can also fall into the niche category and will usually depend on the role you apply for.

... memory overhead. DataFrames for very large datasets (i.e., 100GB+) can be very slow to index and **search** through.
Libraries
There are several different implementations of DataFrames.

... // set left child

Problem
Given a binary tree (not necessarily a binary **search** tree), check if the tree is symmetric. A tree is symmetric if the nodes on the left mirror the nodes on the right.

... based, which can be limiting for more complex lookups. It effectively doesn't lend itself well to **search** like operations, often needing more than one network call (or REST API call) to do the job.

... determine the left and right borders of the preorder and inorder arrays (similar to a binary tree **search**) instead of creating new sub-arrays.
