Digital Logic Electronic circuits are divided into two categories, digital and analog. An analog quantity varies continuously and digital quantities only have discrete values. Digital systems can process, store, and transmit data more efficiently. But it can only assign discrete values. Many systems use a mix of analog and digital signals. For example, a CD …
Pattern matching finds whether or not a given string pattern appears in a string text. Commonly used pattern matching algorithms are Naive Algorithm for pattern matching and pattern matching algorithm using finite automata. Naive Algorithm for pattern matching PAT and TEXT are two strings with length R and S respectively. This algorithm finds INDEX(P) The …
Different types of string operations are, Substrings A substring is the basic unit of access in a string. Unlike other array elements, substrings have their own meaning. To access a substring we need the following information, Name of the string. Position of the first character of the substring in the given string. length of the …
Computers are capable of processing non-numerical data called character data. In computer terminology, a sequence of characters is called a string. Basic terminology Every programming language consists of a character set. A character set will have alphabets, numbers and special characters. A finite sequence of zero or more characters from the character set is called …
Big O notation is a symbolism used in complexity theory to describe theasymptotic behavior of functions. Basically, it tells you how fast a function grows or declines. Suppose M is an algorithm and n is the size of the input data. As n increases the complexity, f(n), of M also increases. The rate of increase …
