What is PHP? PHP (Hypertext Preprocessor) is a widely used server-side scripting language for web development. It allows developers to embed code within HTML files, enabling the creation of dynamic web pages and interactions with databases. PHP is known for its simplicity, versatility, and extensive integration capabilities with popular databases. It offers a broad range of extensions and has a large community of developers, ensuring ample resources and support. Using date_diff() Function In PHP, the date_diff() function is used to calculate the difference between two DateTime objects. It returns a DateInterval object representing the difference between the two dates. ... Read More
In PHP, the double equals (==) and triple equals (===) are comparison operators used to compare values for equality. However, they differ in terms of their behaviour and the level of strictness in the comparison process. Double Equals (==) The double equals operator checks for equality between two values, but it performs type coercion if the two values have different data types. This means that PHP will attempt to convert the values to a common type before performing the comparison. Here are some key points about the double equals operator: If the two ... Read More
The array in the C programming language has a fixed size, which means that once the size is specified, it cannot be changed; you can neither shrink it or extend it. As we know, an array is a group of identically data-typed elements kept in consecutive memory regions. Given an array of values v[] and a binary array a[]. The objective is to use as many k coins to divide the binary array as much as is possible while ensuring that each segment has an equal amount of 0s and 1s. i and j are the neighboring indices of the ...

The aim of this article is to implement a program to decode a given string by removing duplicate occurrences. As you are aware of what a string is, a string is nothing but a collection of characters. Also there is no restriction in the repetitions of characters in a string. A string can have the same character occurring multiple times. In this we will figure out a way to decode a given encoded string str by removing duplicate occurrences. The objective would be to decode the provided string str, which has been encoded with 'a' appearing just once, 'b' twice, ... Read More

The aim of this article is to implement a program to count of N-length binary strings that are repeated concatenation of a substring. The goal is to determine how many binary strings of the length N can be created by repeatedly concatenating a single substring of a given text, provided a positive integer called N. Problem Statement Implement a program to count of N-length binary strings that are repeated concatenation of a substring. Sample Example 1 Let us take the Input, N = 3 Output: 2 Explanation Listed below are the feasible binary string of length N=3 with ... Read More
Here the problem is to determine the total number of strings of the length N containing characters '0' through '9' provided an integer N with an array of string prefixes pre[]. such that none of the strings can contain the provided prefixes. The aim of this article is to implement a program to find the count of N digit numbers not having given prefixes. A collection of various strings is referred to as an array in the C programming language because an array is a linear grouping of data pieces of a similar type. As we already know, the string ...

In Linux, there are several command line tools that can be used to quickly and easily find files on the file system. These tools are powerful and versatile, allowing users to search for files based on a variety of criteria such as name, type, size, and more. Some of the most popular command line tools for finding files in Linux include ‘find’, ‘locate’, ‘grep’, ‘whereis’, ‘which’, ‘fd’, and ‘ack’. These tools are widely used by system administrators, developers, and power users, to find and locate files in a quick and efficient way. In this topic, we will explore some of ... Read More
What is PHP ? PHP, which stands for Hypertext Preprocessor, is a widely used server-side scripting language primarily designed for web development. It provides developers with a powerful and flexible platform for creating dynamic web pages and applications. PHP can be embedded within HTML code, allowing for seamless integration of server-side functionality with client-side elements. Its syntax is similar to C and Perl, making it relatively easy to learn and use for programmers familiar with those languages. PHP enables the execution of server-side scripts on a web server, generating dynamic content that can be delivered to the user's browser. ... Read More
