3 days ago · Given an array of distinct integers, find length of the longest subarray which contains numbers that can be arranged in a continuous sequence. Examples: Input: arr[] = {10, 12, 11}; Output: Length of the longest contiguous subarray is 3 Input: arr[] = {14, 12, 11, 20}; Output: Length of the longest contiguous subarray is 2 Input: arr[] = {1, 56, 58

5 days ago · This current article follows and extends this line of research: We present the first polynomial-time algorithm that finds the longest common subsequence under CT-matching of two given strings S and T of length n, in O (n 6) time and O (n 4) space for general ordered alphabets.
3 days ago · i have a question that want the minimum length of k that in each consecutive substring of a string with length k, There must be at least one common character. for example if s="abcaca". for k = 1 --> substrings are [a], [b], [c] and etc that we can not find a common char in all. for k = 2 --> [ab], [bc], [ca] ... that again there is no a common ...

4 days ago · Abstract. The numbers we study in this paper are of the form B n, p ( k ), which is the number of binary words of length n that contain the word p (as a subsequence, not necessarily consecutive in the word) exactly k times. Our motivation comes from the analogous study of pattern containment in permutations.
5 days ago · Definition. A constant-recursive sequence is any sequence of integers, rational numbers, algebraic numbers, real numbers, or complex numbers (written as as a shorthand) satisfying a formula of the form.
