The aim of this article is to implement a program to print the number of camel case character present in a given string. As you all know, a string is a collection of characters. Now let us see what camel case letters are. Programming languages like Java utilise a naming style called camel case. That is, It includes entering multi-word identities without spaces or underscores, having the initial word in lowercase with successive words in uppercase. Code written in this manner is easier to read and understand. The inner uppercase letters, which resemble camel humps, are what give the name ... Read More
The challenge is to display the top five probable plain texts which could be decrypted from the supplied monoalphabetic cypher utilizing the letter frequency attack from a string Str with size K representing the given monoalphabetic cypher. Let us see what exactly is frequency attack. The very foundation for frequency analysis is the certainty that specific letters and letter combinations appear with varied frequencies all through any given section of written language. Additionally, matter-of-factly every sample of that language shares a common pattern in the distribution of letters. To make it more clear, The English alphabet has 26 letters, ... Read More
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
