Manacher (1975) invented an ()-time algorithm for listing all the palindromes that appear at the start of a given string of length . However, as observed e.g., by Apostolico, Breslauer & Galil (1995) , the same algorithm can also be used to find all maximal palindromic substrings anywhere within the input string, again in O ( n ) {\displaystyle ...
In computer science, the shunting yard algorithm is a method for parsing arithmetical or logical expressions, or a combination of both, specified in infix notation.It can produce either a postfix notation string, also known as reverse Polish notation (RPN), or an abstract syntax tree (AST). [1]
In computer science, an in-place algorithm is an algorithm that operates directly on the input data structure without requiring extra space proportional to the input size. In other words, it modifies the input in place, without creating a separate copy of the data structure.
In theoretical computer science, the separating words problem is the problem of finding the smallest deterministic finite automaton that behaves differently on two given strings, meaning that it accepts one of the two strings and rejects the other string. It is an open problem how large such an automaton must be, in the worst case, as a ...
Range minimum query reduced to the lowest common ancestor problem.. Given an array A[1 … n] of n objects taken from a totally ordered set, such as integers, the range minimum query RMQ A (l,r) =arg min A[k] (with 1 ≤ l ≤ k ≤ r ≤ n) returns the position of the minimal element in the specified sub-array A[l …
Using the XOR swap algorithm to exchange nibbles between variables without the use of temporary storage. In computer programming, the exclusive or swap (sometimes shortened to XOR swap) is an algorithm that uses the exclusive or bitwise operation to swap the values of two variables without using the temporary variable which is normally required.
To fix this problem, is padded with a terminal symbol not seen in the string (usually denoted $). This ensures that no suffix is a prefix of another, and that there will be n {\displaystyle n} leaf nodes, one for each of the n {\displaystyle n} suffixes of S {\displaystyle S} . [ 8 ]
Given an input string S = ^ BANANA $ (step 1 in the table below), rotate it N times (step 2), where N = 8 is the length of the S string considering also the red ^ character representing the start of the string and the red $ character representing the 'EOF' pointer; these rotations, or circular shifts, are then sorted lexicographically (step 3).
