Extracting floating numbers from text/string can be done using Python’s regular expressions which provides a flexible and effective way to parse numerical data embedded in strings. Regex can be customized to extract floating-point numbers, whole numbers, or complex patterns based on your specific needs. The regular expression used in the example is: import re r"[-+]?\d*\.\d+|\d+" Let’s break down each parameter: '[-+]?': This allows for an optional sign (`+` or `-`) at the start of the number. '\d*\.\d+': matches zero or more digits before the decimal point. ... Read More
The re.finditer() method in Python's 're' module finds all occurrences of a specified pattern in a string. It returns an iterator containing match objects for each occurrence. This method is especially useful when you need to determine the position of each match within the input string. Following is the syntax for re.finditer() method. re.finditer(pattern, string, flags=0) How to Use 're.finditer()' Method Following are the steps involved in using re.finditer() method. Import the re module: You need to import the regular expression module before using it. ... Read More

Recursive Factorial Calculation A strong number is a number, where the sum of the factorial of its digits equals the number itself. In C programming, a factorial is the product of all positive integers less than or equal to a given number. To calculate the factorial of a number, we use a recursive function with the argument N. This function will repeatedly call itself with a decremented value of N, multiplying the results until it reaches 1. 123!= 1!+2!+3! =1+2+6 =9 In this case, 123 is not a strong number because the sum of the factorial of its digits ...

In this article, we will learn to sort ArrayList of custom objects by property in Java. The ArrayList class extends AbstractList and implements the List interface. ArrayList supports dynamic arrays that can grow as needed. Problem Statement ArrayList is created with an initial size. When this size is exceeded, the collection is automatically enlarged. When objects are removed, the array may be shrunk. Below is a demonstration of the same − Input − The list is defined as Java Scala Python Mysql Output − The list after sorting values: Java Mysql Python Scala ... Read More
In this article, we will learn to convert milliseconds to readable strings in Java. Converting milliseconds into a human-readable format such as hours, minutes, seconds, and milliseconds is a common programming task, especially in time-sensitive applications. Problem Statement The challenge is to convert a given time in milliseconds into a readable string that shows hours, minutes, seconds, and remaining milliseconds. Input long millis = 5000000; Output Hours = 1 Minutes = 23 Seconds = 20Milliseconds = 0 1 hr(s) 23 min(s) 20 sec(s) 0 ms Approaches to convert millisecond to readable string Following are the two different approaches to converting milliseconds ...

In MySQL, the ENUM is a data type that is used to create a column with a fixed set of values. It is helpful for the fields that have limited alternatives, such as categories, statuses, and color codes. In the ENUM data type, if you do not declare NOT NULL then it gives the default value NULL or Empty String('') when inserting records without specifying a value. However, if you declare NOT NULL and don't specify the values when inserting then it gives the first value from the ENUM. Following is the syntax to create a table that has ... Read More
Yes, you can include a string value with spaces in ENUM type. This is particularly useful when we add descriptive options that contain multiple words. Let us explore how to create, describe, and use ENUM columns containing spaces, with supporting examples. ENUM vs VARCHAR: While both ENUM and VARCHAR can store strings with spaces, ENUM has an advantage: limiting of the number of entries that can be added into a column to a fixed set. Because of this, it is useful in situations where the values are limited and static, such as size categories, and status codes. Whereas VARCHAR is ... Read More
