String Searching Functions The C string functions are built-in functions used for various operations and manipulations on strings. These functions perform tasks such as copying, comparing, concatenation, and determining the length of strings. The library also provides several string-searching functions, which are included as follows − Function Description ... Read More
When we start learning to code, practicing star patterns is one of the best ways to improve logic building. One of the simplest yet fascinating patterns is the hollow square pattern. In this article, we are going to learn how to print a Hollow Square Pattern using C++. What is Hollow Square Pattern? A hollow square pattern is a geometrical arrangement of stars forming a square shape, but the stars are present only at the boundary of the square. The stars are printed in such a manner that the edges of the square are filled with stars, while the interior ... Read More
To design Credit Card UI Design in HTML & CSS, we will begin with creating the structure of the Credit Card UI with the help of html. And we will design the html in the credit card with the help of css. In this article, our task is to design a credit card UI design in HTML and CSS. Steps to Create Credit Card UI Design To design a credit card UI in HTML and CSS, we will create two files: HTML Code for Structure CSS Code for Styling ... Read More
In this tutorial, we will learn how to find the maximum length of the subsequence having the same left and right rotations in Java. We find the maximum length of such subsequence. Finding the longest subsequence with identical or alternating digits We will solve the problem based on a particular observation. The strings can only have the same left and right rotations if all digits of strings are equal or it contains the two digits alternatively, and the string length is even. Step 1: Initialize Variables: Initialize the len variable with the string length and ... Read More
In this article, we will explore how to perform arithmetic operations between BigDecimal and Primitive data types by using Java. For instance, Addition: The sum of a BigDecimal object with a value of 10.50 and an int primitive with a value of 5 is a BigDecimal object with a value of 15.50. 10.50 + 5 = 15.50 SyntaxThe syntax doubleValue() method returns the value of a BigDecimal object as a double primitive type. double doubleNum1 = num1.doubleValue(); Where “num1” is a BigDecimal object. What is BigDecimal in Java? BigDecimal is a class in Java's java.math package that ... Read More
In this article, we will learn how to count inversions of size three in a given array. The goal is to find how many triplets (i, j, k) exist such that i < j < k and arr[i] > arr[j] > arr[k].Understanding Inversion Count Inversion count is a step-counting method by which we can calculate the number of sorting steps taken by a particular array. It is also capable of counting the operation time for an array. But, if we want to sort an array in a reverse manner, the count will be the maximum number present in that array. Array: ... Read More
In this article, we will learn how to implement binary search on a float array in Java using the Arrays.binarySearch() method. Binary search on a float array can be implemented by using the method java.util.Arrays.binarySearch(). This method returns the index of the required float element if it is available in the array, otherwise, it returns (-(insertion point) - 1) where the insertion point is the position at which the element would be inserted into the array. Java.util.Arrays.binarySearch(). methodThe Arrays.binarySearch() method in Java searches for a specified element in a sorted array. It returns the index of the element ... Read More
In this article, we will understand how to convert the ArrayList into a string and vice versa. The ArrayList class is a resizable array, which can be found in the java. util package. The difference between a built-in array and an ArrayList in Java is that the size of an array cannot be modified. ArrayList definitionAn ArrayList in Java is a resizable array found in the java.util package, which allows for dynamic modifications in size as elements are added or removed. It supports ...

In this article, we will learn how to retrieve the major version of the JDBC driver using the getJDBCMajorVersion() method of the DatabaseMetaData interface in Java. This method is useful for checking the version of the JDBC driver in use. getJDBCMajorVersion() method The getJDBCMajorVersion() method of the DatabaseMetaData interface returns the major version of the JDBC driver in integer format. To get a major version of the JDBC driver − Make sure your database is up and running. ... Read More
In this article, we will learn how to convert a string to a float-type number in Java. We will use the Float.parseFloat() method to perform this conversion. Float.parseFloat() method The Float.parseFloat() method belongs to the Float class in Java and is used to convert a string representation of a number into a primitive float. If the string does not contain a valid float representation, it throws a NumberFormatException. NumberFormatException: Thrown to show that the application has attempted to convert a string to one of the numeric types, but that the string does not have the appropriate format. ... Read More
