For example say we have an array Arr[5] = {1, 2, 3, 4, 5} and i am looking for 3 here in the array Arr. So 3 is the searching element. Last edited on Dec 14, 2016 at 12:10pm Dec 14, 2016 at 12:29pm Chervil (732
The WHERE function is an essential tool for doing fast conditional array operations in IDL. Most operations that could be done in a Fortran-like style using FOR loops and IF statements can be done faster and more elegantly in IDL using WHERE. WHERE applies the logical test to every element ...
The NumPy lexort() function performs an indirect sort using a sequence of keys. The keys can be seen as a column in a spreadsheet. The function returns an array of indices, using which the sorted data can be obtained. Note, that the last key happens to be the primary key of sort....
Thearray_searchfunction searches for a value in an array. It returns the key of the found element or false if not found. The search is case-sensitive for strings. Syntax:array_search(mixed $needle, array $haystack, bool $strict = false): mixed. The strict parameter enables type comparison...
The following is an example JSON response from GetFaceSearch. The response includes an array of people (Persons) detected in the video whose faces match a face in the input collection. An array element, PersonMatch, exists for each time the person is matched in the video. Each PersonMatch ...
The property of S we want to establish now becomes that with high probability, any set in ℛ of size at least C(n/r) log r contains an element of the sample S. With this motivating example, we can proceed to the general framework. One considers a ground set X and a system ℛ ...
array.some - See if at least one element in the array satisfies a predicate. array.reduce - Apply a function to reduce the array to a single value (from left-to-right). array.reduceRight - Apply a function to reduce the array to a single value (from right-to-left). Installing If yo...

We will go through the quicksort and quickselect algorithms for sorting and selecting the kth smallest element in an array efficiently. This will also be an introduction to the role of randomization in algorithm design. Next, we will study hashtables: a highly useful data structure that allows...
