You are given a string s consisting of lowercase letters and an integer k. We call a string t ideal if the following conditions are satisfied:t is a subsequence of the string s.The absolute difference in the alphabet order of every two adjacent letters in t is less than or equal to k.Return the length of the longest ideal string.A subsequence is a string that can be derived from another string by deleting some or no characters without changing the order of the remaining characters.Note that the alphabet order is not cyclic. For example, the absolute difference in the alphabet order of 'a' and 'z' is 25, not

Given a string s of length n, find all the possible subsequences of the string s in lexicographically-sorted order.

Raju is preparing questions for the internal test. While creating questions, he gave one such question to his son Arun to solve. Raju has given the string S to his son Arun. Arun's task is to print the size of the longest possible substring that has exactly K unique characters.ExampleInput:String = aabacbebebe; K = 3Output:The substring will be cbebebe with length 7. Explanation:The unique characters in the string are: 'a', 'b', 'c', and 'e'. The longest subsequence with at most 3 distinct characters is "aabacbe". It contains the characters 'a', 'b', and 'c', which is the maximum number of distinct characters allowed (k = 3). Therefore, the length of the longest subsequence is 7.Input format :The first line of input consists of the string S.The second line of input consists of the integer K.Output format :The output prints the size of the longest possible substring that has exactly K unique characters.Refer to the sample output for the formatting specifications.Code constraints :1≤ string length ≤ 501≤ K ≤10Sample test cases :Input 1 :aabacbebebe3Output 1 :7Input 2 :abbc1Output 2 :2

Given two integers N and K, the task is to find the string S of minimum length such that it contains all possible strings of size N as a substring. The characters of the string should be from integers ranging from 0 to K-1.  Example 1:Input:N = 2, K = 2Output: 00110Explanation: Allowed characters are from 0 to k-1 (i.e., 0 and 1).There are 4 string possible of size N=2 (i.e "00", "01","10","11")"00110" contains all possible string as a substring. It also has the minimum length.Example 2:Input:N = 2, K = 3Output: 0010211220Explanation: Allowed characters are from 0 to k-1 (i.e., 0, 1 and 2).There are total 9 strings possibleof size N, given output string has the minimumlength that contains all those strings as substring.Your Task: You don't need to read input or print anything. Complete the function findString( ) which takes the integer N and the integer K as input parameters and returns the string.Note: In case of multiple answers, return any string of minimum length which satisfies above condition. The driver will print the length of the string. In case of wrong answer it will print -1.Expected Time Complexity: O(KNlogK)Expected Space Complexity: O(KNN)Constraints:1 ≤ N ≤ 41 < K < 101 < KNN < 106

Given two strings text1 and text2, return the length of their longest common subsequence. If there is no common subsequence, return 0.A subsequence of a string is a new string generated from the original string with some characters (can be none) deleted without changing the relative order of the remaining characters.For example, "ace" is a subsequence of "abcde".A common subsequence of two strings is a subsequence that is common to both strings. Example 1:Input: text1 = "abcde", text2 = "ace" Output: 3 Explanation: The longest common subsequence is "ace" and its length is 3.

Given a string S consisting of only lowercase characters, find the length of the longest substring that does not contain any vowel.Input FormatFirst line of input contains T - number of test cases. Its followed by T lines, each line contains a string of size N, containing only lowercase english alphabets.Output FormatFor each test case, print the length of the largest substring that does not contain any vowel, separated by newline.Constraints1 <= T <= 1001 <= N <= 104
