In Java, smaller datatype can be converted to bigger datatype. Here, we will see how to convert char datatype to int datatype. The char data type is a single 16-bit Unicode character. It has a minimum value of '\u0000' (or 0) and a maximum value of '\uffff' (or 65, 535 inclusive). The int data type is a 32-bit signed two's complement integer, which has a minimum value of -231 and a maximum value of 231-1. Let's deep dive into this article, to know how it can be done by using Java programming language. For instance Suppose the given ... Read More

In Python, a set is an unordered collection of unique elements, represented by {}. It allows efficient membership testing and eliminates duplicate values, making it useful for tasks such as removing duplicates or checking for common elements between sets. In this article, we will learn a python program to find the most common elements set. Methods Used The following are the various methods to accomplish this task: Using for loop and set.intersection() function Using list comprehension, max() and intersection() functions Demonstration Assume we have taken an input list containing sets. We will now get the most ... Read More

In Python, strings are a fundamental data type used to represent sequences of characters. They are enclosed in single quotes ('') or double quotes ("") and offer a wide range of operations and methods for manipulation Example Assume we have taken an input string. We will now find the maximum scoring word from an input string using the above methods. Input inputString = "hello tutorialspoint python users and learners" Output Resultant maximum scoring word from the input string: tutorialspoint In the above input string, the sum of characters' positional values of the word tutorialspoint is having the ...

In Python, a dictionary is a built-in data structure that stores data in key-value pairs. It allows efficient retrieval and modification of values based on their corresponding keys. Each key in a dictionary must be unique, and it is associated with a specific value. A dictionary of lists is a dictionary where the values associated with each key are lists. This means that each key maps to multiple values, and those values are stored as elements within a list. On the other hand, a list of dictionaries is a list that contains multiple dictionaries as its elements. Each dictionary within ... Read More

In Java, a matrix can be represented using a two-dimensional array. Matrices are used for storing and manipulating data that have a tabular structure. Matrices have several properties and operations associated with them, such as addition, subtraction, multiplication, transposition, and determinant calculation. As per the problem statement we have to Create a Matrix and Fill Primary Diagonal with 1 and Secondary Diagonal with 0. Let's start! For instance Suppose we have 4*4 matrix i.e. 4 rows and 4 columns. After performing the operation on matrix, the result will be: Enter the size of the matrix: ... Read More

NumPy is a Python library for numerical computing that provides efficient array operations, and numpy.reshape() is a function used to change the shape of an array, with -1 indicating an inferred dimension. When working with arrays, we frequently get into instances where we need to modify the shape of the array, but doing so requires copying the data first, then arranging it into the required shape which is time taking. Fortunately, Python has a function called reshape() that may help with this. Example 1: Find Unknown Dimensions in Numpy We are only allowed to have one "unknown" dimension while we ... Read More

As per the problem statement, we have to create an empty matrix and fill that matrix with the prime numbers starting from the smallest prime number i.e. 2. A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself. For instance, let's take the number 7. When we divide 7 by any number other than 1 and 7, we get a remainder. For example, dividing 7 by 2 gives a remainder of 1, and dividing 7 by 3 gives a remainder of 1 as well. Therefore, 7 has no divisors other ... Read More

The meaning of value key assignment in Python is the process of associating a value with a specific key within a dictionary, allowing efficient retrieval and manipulation of data based on key-value pairs. It enables the creation and organization of structured data structures for various purposes Python's implementation of a data structure known more commonly as an associative array is a dictionary. A dictionary is made up of a group of key-value pairs. Each key-value combination corresponds to a key and its corresponding value. Example Assume we have taken two input dictionaries with the same keys. We will now compare ... Read More

A byte string is similar to a string (Unicode), except instead of characters, it contains a series of bytes. Applications that handle pure ASCII text rather than Unicode text can use byte strings. Converting a byte string to a list in Python provides compatibility, modifiability, and easier access to individual bytes. It allows seamless integration with other data structures, facilitates modification of elements, and enables efficient analysis and manipulation of specific parts of the byte string. Demostration Assume we have taken an input byte string. We will now convert the given byte string to the list of ASCII values ... Read More

An array(list) of comma-separated values (items) enclosed in square brackets is one of the most flexible data types available in Python. The fact that a list's elements do not have to be of the same type is important. In this article, we will learn a python program to check if any key has all the given list elements. Example Assume we have taken an input dictionary and a list. We will now check whether the values of any key of the input dictionary contain given list elements using the above methods. Input inputDict = {'hello': [4, 2, 8, 1], 'tutorialspoint': ... Read More
