- For Letter -> A | B Digit -> 0 | 1 Id -> letter (letter | digit)* Generate NFA and transfer it to DFA.Many encoded strings contain delimiters. A delimiter is a non-empty string that acts as a boundary between different parts of a larger string. The delimiters involved in this question occur in pairs that must be balanced, with each pair having an open delimiter and a close delimiter. There will be only one type of delimiter for each string. The following are examples of delimiters.Example 1Expressions in mathematics use open parentheses "(" and close parentheses ")" as delimiters. For each open parenthesis, there must be a matching close parenthesis.(x + y) * 5 is a valid mathematical expression.(x + (y) is NOT a valid mathematical expression because there are more open delimitersthan close delimiters.HTML uses <B> and </B> as delimiters. For each open delimiter <B>, there must be a matching closeExample 2 delimiter </B>.<B> Make this text bold </B><B> Make this text bold </UB>is valid HTML.is NOT valid HTML because there is one open…Given two strings S of length n and T of length m, we want to reconstruct T from S with a minimum number of the following operations: i) delete a character from S, ii) insert a character into S, or iii) swap two consecutive characters in S. For example, when S = yorkun and T = ayokru, one can insert an 'a' at index 1 of S, swap 'r' and 'k' in S, and remove 'n' from the end of S. Therefore, we can reconstruct T from S with 3 operations. Devise a DP solution to report the minimum number of operations to reconfigure S to T. The actual operations in a minimum-cost reconfiguration are not needed. It suffices to show Steps 1 and 2 in the DP paradigm in your solution. In Step 1, you must specify the subproblems, and how the value of the optimal solutions for smaller subproblems can be used to describe those of large subproblems. In Step 2, you must write down a recursive formula for the minimum number of operations to reconfigure. Assume indices start at 1.
- Let the string having length eight of an arrays is defined as ; 01001010 , 01101101 Apply the definition of Tautology and Conjunction on it.A substring of a string is a contiguous sequence of characters from the string. For example, BC is a substringof ABCD which starts from the second character of ABCD. Another example, ABC is a substring of ABCD whichstarts from the first character of ABCD. Note that ABCD itself is also a substring of ABCD.In this problem, we define a special substring as a non-empty substring that contains only the same character.For example, B and CC are special substrings of ABBCCC, while ABBC and BC are not special substrings.You are given a string S of length N and an integer K. Your task is to determine the minimum number ofcharacters of S that need to be changed such that there exists a special substring of length K in S.For example, let N = 6, K = 4, and S = ABBCCC. In this example, we only need to change the third characterof S to C (i.e. ABBCCC → ABCCCC) so that we have a special substring CCCC of length 4.InputInput begins with a line containing two integers: N K (1 ≤ K ≤ N ≤ 100 000)…Construct a set S of strings in lowercase (R = 26) for which the R-way trie uses space (in words) less than the total number of characters in strings in S. (The number of characters in the set {abc, bcd, aabd} is 10.)
- Bell has a binary string S of length N. He can perform the following operation on the string: Choose any substring of S; Remove the chosen substring from S; Concatenate the remaining parts of the string S, obtained after removing the substring. Find the length of the longest prefix having all 1s you can achieve, by performing the above operation at most once. Note: A prefix of a string is obtained by deleting some (possibly zero) characters from the end of string S. Input Format The first line of input will contain a single integer T, denoting the number of test cases. Each test case consists of multiple lines of input. The first line of each test case contains a single integer N, the length of the binary string. The next line contains the binary string S. Output Format For each test case, print in a new line, the length of the longest prefix having all 1s you can achieve, by performing the operation at most once. Constraints 1≤T≤1000 2≤N≤2⋅105 S contains 0 and 1 only. The sum…Given a string s that is input as a character array, (i) reverse the string and(ii) check if it is a palindrome. A palindrome is a string that reads the same forwardand backward, for example, “MADAM”.Write a regular expression for the set of strings over the alphabet {a, b} that have at least one a andat least one b. For example, aaaba and bbaba are strings in the set, but aaaa and bbb are not.
- The Reflection algorithm can be used to encrypt a C-string (character array terminated with the null character) before it is transmitted over the Internet. The Reflection algorithm works as follows: Each letter in the message is converted to the letter in that is 13 positions to the right of that letter in the English alphabet. If the end of the alphabet is reached, counting continues from the first letter in the alphabet. The case of the letters must be maintained. For example,'M' →'Z', 'x' → 'k', 'A' → 'N'The numeric characters ('0' to '9') are shifted 5 positions to the right of that number in the character set '0' to '9'. If ‘9’ is reached, counting continues from ‘0’. For example,'0' → '5', '2' →'7', '8' → '3' All other characters are left as they are. a) What would the following string be encrypted to by the Reflection algorithm?“Call me at 662-2002 Ext 85393” b) Write a function, getPosition, which finds the position of a letter in the alphabet regardless of the case of the…Given E = {a, 6, c}, and E, = {1, 2}. List three strings of E o E.How many non-empty contiguous substrings does a string of length n have? For example, “cde” is a contiguous substring of the string “abcdefg” whereas “ace” may be considered a substring of “abcdefg” but is NOT a contiguous substring of “abcdefg”. Notice that the order of the characters in the string must be preserved in any substring.
