The indices are the position of the elements present in the list whereas K defines the specific value to target the smallest element from the list. Sometimes, we are working in the field of web development and database these tasks generally occur to solve this problem statement. In Python, we have built-in functions like sorted(), range(), len(), etc. that will be used to find the indices for k Smallest elements. Syntax The following syntax is used in the examples- sorted() The sorted() is an in-built function in Python that helps to return the new sorted list while ... Read More
The position of the smallest value within a list is indicated by the index of the minimum element. Each list element has a distinct index that increases by one with each additional element after the first, starting at zero for the first element. By determining the index of the minimum element, we can locate the exact position of the smallest value within the list. In Python, we have some built-in functions like min(), index(), argmin(), lambda(), and, enumerate() to find the index of the minimum element in the list. Syntax The following syntax is used in the examples- min() ... Read More
Lists are a powerful data structure in Python that can hold many values of various types. We may come across nested lists where the items themselves are lists. In such circumstances, flattening the list and retrieving individual elements from the hierarchical structure may be essential. In Python, we have some built-in functions- chain(), extend(), and append() that can be used to solve the Flatten List to individual elements. Let’s take an example of this: Input # Flatten List my_list = [[11, 21, 31], [20, 30, 40], [4, 5, 6], [1, 2, 3]] Output # individual element in the list ... Read More
In this article, we will learn how to use named arguments in javascript, and how we can use it to significantly enhance code readability and maintainability. Javascript allows us to use named arguments, which eliminate the need for the order of parameters to matter during function execution. We may then access the arguments by name inside the function definitions. Let’s look at some of the examples and methods to understand the concept better − Example 1 - Passing Objects as Arguments We can pass an object as an argument to the function to achieve named−argument functionality. This uses the ... Read More
The dictionary is one of the famous datatypes of Python that consist of keys with value pairs. The strings list is the set of elements that are represented either in a single or double quotation. In Python, we have some built-in functions such as keys(), set(), intersection, and append() will be used to find the dictionary keys present in strings List. Let’s take an example of this. There are two available sets:- The given dictionary, {'T': 1, 'M': 2, 'E': 3, 'C': 4} The given list, [T, A, B, P, E, L] Therefore, the final result becomes [T, E]. ... Read More
The tuple is a popular datatype of Python that represents the collection of objects or elements separated by commas. The frequency of data type defines the total number of counts of a specific variable type. Python has four primitive variable types: integer, float, boolean, and string. In Python, we have some built-in functions such as type(), isinstance(), filter(), lambda, len(), and list() will be used to Find the frequency of a given Datatype in a Python tuple. Syntax The following syntax is used in the examples- type() The type() is an in-built function in Python that returns the type ... Read More
We will learn how to utilise imports and exports in javascript in this post, as well as how to use them to break our code into different modules in order to better organise it. To facilitate modular development in programming, which enables us to organise our code into reusable modules, JavaScript provides exports and imports. To achieve this sharing and reusability of code, we can use different types of exports and imports. Exports allow us to make functions, variables, objects, or any values available outside of a module. By marking components as exports, we can expose them for use in ... Read More
The stream of strings is a sequential flow of given data where an individual element of the stream represents a string. The stream allows a large process of string data In C++, we have some STL(Standard template library) based functions such as count() and insert() to Check duplicate in a stream of strings. Using Standard Template Library The program uses C++ STL to set the header file unordered representing the unique key element and helps to solve the duplicates in a stream of strings. Syntax The following syntax is used in the examples- static unordered_set unq_string; The ... Read More
In this article, we will learn about the various ways to define and declare variables in javascript, and how we can use them to implement state management in our applications. In javascript, variables can be thought of as containers that hold values, and which can be retrieved later on in the application. There are several ways to define a variable, each with its own syntax and use cases. Let’s understand different methods of doing so with the help of some examples to understand the concept better. Example 1: Using the var keyword The “var” variable has function scope, which means ... Read More
In this article, we will learn how to read cookies in javascript, and how we can use it to implement certain features such as user tracking, user preference, personalized experience, etc. Cookies are small pieces of data stored in a user's web browser. In javascript, we can read cookies using document's cookie property and extract the desired information using destructuring. Let’s look at some of the examples to understand the concept better − Example 1 - Reading All Cookies In this example, we will − read all cookies by accessing the document.cookie property and log them to the console. ...
