- Consider the alphabet set Σ = {a b}; Write Regular Expressions for the followingdefinitions.1. Language of All those words which do not contains double a’s.2. Language of All those words which do not contains double letters.3. Language of All those words which has at most three letters.4. Language of All those words which do not contains substring ab.5. Language of All those words in which total number of a’s are divisible by 5 6. Language of All those words which do not contains substring baa.7.

Language of All those words which contains ODD a’s and ODD b’sPROLOG LANGUAGE We flatten a list L by first removing all lists within L and replacing them with their members. Write a Prolog rule flattenit/2 which flattens a list. Note: there is a built-in called flatten - you should not use that in your answer. For example: :- flattenit([a,b,c,[d,e],f,[c, a, b]], [a,b,c,d,e,f,c,a,b]). :- flattenit([1,2,3,4,[5,6,[7,8]]], [1,2,3,4,5,6,7,8]). :- flattenit([1,2,[3,4,[5,6],7],8,[2,4,5,8]], [1,2,3,4,5,6,7,8,2,4,5,8]).Assignment Content Given two strings s and t, determine if they are isomorphic. Two strings s and t are isomorphic if the characters in s can be replaced to get t. All occurrences of a character must be replaced with another character while preserving the order of characters. No two characters may map to the same character, but a character may map to itself. Example 1: Input: s="egg", t = "add" Output: true Example 2: Input: s="foo", t = "bar" Output: false Example 3: Input: s= "paper", t = "title" Output: true

- Correct answer will be upvoted else downvoted. Assume you are given two strings an and b. You can apply the accompanying activity quite a few times: pick any adjacent substring of an or b, and sort the characters in it in non-dropping request. Let f(a,b) the base number of activities you need to apply to make them equivalent (or f(a,b)=1337 in case it is difficult to make an and b equivalent utilizing these tasks). For instance: f(ab,ab)=0; f(ba,ab)=1 (in one activity, we can sort the entire first string); f(ebcda,ecdba)=1 (in one activity, we can sort the substring of the subsequent string beginning from the 2-nd character and finishing with the 4-th character); f(a,b)=1337. You are given n strings s1,s2,… ,sk having equivalent length. Compute ∑i=1n∑j=i+1nf(si,sj). Input :The principal line contains one integer n (1≤n≤2⋅105) — the number of strings. Then, at that point, n lines follow, each line contains one of the strings si, comprising of lowercase Latin…The conjugations for all Spanish regular verbs can be built by using the three forms for verbs ending in -ar, -er and -ir. Create a function that takes a verb as string, and returns a string with the six person/number combinations (like in the examples). Watch out for verbs ending in -ir (check the notes). Try programming the construction rather than forming structures with arrays. Examples espVerb("pasar") → "Yo paso, tú pasas, él pasa, nosotros pasamos, vosotros pasá espVerb ("unir") → "Yo uno, tú unes, él une, nosotros unimos, vosotros unís, ell espVerb ("correr") → "Yo corro, tú corres, él corre, nosotros corremos, vosotros The smallest category of regular Spanish verbs is those that end in -ir. To conjugate them, remove the infinitive ending and then add one of the following verb endings: Singular Plural 1st person yo -o 2nd person tú -es 3rd person él -e *** Notes nosotros -imos vosotros -ís ellos -en • This is for European Spanish, so the second person plural is vosotros pasais,…Log There was a storm recently on Jolibi village. The storm was so strong that some treesfell. There are some logs of varied length lying on the ground. The village ground canbe represented by a string of length N, where the i-th character is either 1 or 0. A singlelog is represented by consecutive characters of 1, and two different logs are separated byone or more 0. For example, for the string 1100010111, there are 3 logs. The first one atposition 1 to 2 with length 2, the second one at position 6 with length 1, and the thirdone at position 8 to 10 with length 3.As a carpenter, you want to take one of these logs home. Because you are the seniorcarpenter, you may take the longest log home. Determine the length of the longest log! Format InputThe first line contains an integer N, the length of the string. The next line contains a string of length N, which represents thevillage ground. Format OutputOutput an integer X, the length of the longest log. Constraints• 1 ≤ N ≤ 104• the i-th…
- Write a function in Prolog called isPair.The function should take an array/list of values. It should return true if the list has pairs of equal numbers and false if not. For example, isPair([1,1,2,2,3,3]) is and isPair([1,1,1,1]) is true and isPair([5,5,5]) is false. no hand writtenIn using, lists as sets, we wish to judge the list (a b c) and (b c a) as equal because they contain the same elements. Also, we wish to judge sets that contain sets, such as ( a (b c d) e), to be equal to ( e a (c d b)). Implement a scheme predicate called set-equal? that takes as input two lists representing sets and returns true if the lists represent the same set and false otherwise. The difference between this predicate and the one discussed in detail in class is that this predicate will support sets of sets to any degree of nesting, e.g., sets of sets of sets. Thus, the call (set-equal? ‘(a (b (c d))) ‘( ((d c) b) a)))) should return #t and the call (set-equal? ‘(a (b (c d))) ‘( (d c b) a)))) should return #f. Racket code only please.
