You are given a sequence of left and right parentheses of length n. Design a data structure which supports operations "toggle the parenthesis at position ?" (in time O(log n)) and “report whether the sequence is proper” (in O(1)). (A sequence of parentheses is proper if we never close a parenthesis that wasn't opened previously, as we read the sequence from left to right.)

- A postfix expression is an expression in which each operator follows its operands. Figureabove shows an examples of postfix expressions.The advantage of postfix form is that there is no need to group subexpressions in parentheses or to consider operator precedence. One may have used pocket calculators that require entry of expressions in postfix form.Write a program that simulates the operation of a calculator by scanning an integer expression in postfix form and displaying its result. The program should push eachinteger operand onto the stack. When an operator is encountered, the top two operands are popped, the operation is performed on its operands, and the result is pushed back onto the stack. The final result should be the only value remaining on the stack when the end of the expression is reached. This program scans a postfix expression and evaluates it. The Postfix expression must be followed by a space and a '?' to mark the end of the expression. One must use stack and the…A spell checker in a word processing program makes suggestions when it finds a word not in the dictionary. To determine what words to suggest, it tries to find similar words. One measure of word similarity is the Levenshtein distance, which measures the number of substitutions, additions, or deletions that are required to change one word into another. For example, the words spit and spot are a distance of 1 apart; changing spit to spot requires one substitution (i for o). Likewise, spit is distance 1 from pit since the change requires one deletion (the s). The word spite is also distance 1 from spit since it requires one addition (the e). The word soot is distance 2 from spit since two substitutions would be required. a. Create a graph using words as vertices, and edges connecting words with a Levenshtein distance of 1. Use the misspelled word “moke” as the center, and try to find at least 10 connected dictionary words. How might a spell checker use this graph? b. Improve the method…Please Answer in C++ language only Today the chef decided to cook some tasty dishes from the ingredients in his kitchen. There is an NN of components, represented by the strings S1,S2, .... SN. The chef took all the ingredients, put them in a cauldron and mixed them. In the cauldron, the letters of the strings representing the ingredients are completely shuffled, so that each letter appears in the cauldron as many times as it has appeared in all the strings combined; now the cook can take out one letter from the cauldron at will (if that letter appears in the cauldron more than once, it can be taken out that many times) and use it in a dish.

- Write a recursive function that returns a value of 1 if its string argument is apalindrome and zero otherwise.* Note that for the function parameters, you need to accommodate for the shrinkingstring, so that the string shrinks both from beginning and end after each recursive call.** Think about the simple cases or base cases. The 2 base cases have conditions thatwould return 0 and return 1 independently.For the palindrome, create a driver program. First ask the user to enter anystring through the keyboard. Then remove all the spaces and punctuations from thestring. Also, remove any letter capitalization from the string. Finally, pass the string tothe palindrome function through a function call.This is a fill in the Blank question. Students will see an empty textbook to type their answer. In the following, x and y are variables, A and B are constants. Fill in the correct substitution such that each of a(A, x) and a(y, B) will be the same expression (this process is called Unification). SUBST{X/ , y/Write program in C++ using strings in conjuction with 2D arrays. Allow the user to enter the names of several local businesses. Sort the business names and display the results. Continue this process until the user is out of business names. Please use good functional decomposition to make your development easier. (Perhaps one function for sorting an array of strings, another function for swapping two strings, one for displaying an array of strings, and others to maintain the user interface. This is also a good place to use a library, btw.) Example Run As an example the program interaction might look something like (the parts in parentheses are typed by the user): $ ./busisort.out Welcome to the Business Sorting Program!!! Please enter the name of a business: (WalMart) Your business is: WalMart Another business? (y) Please enter the name of a business: (JC Penney) Your businesses are: JC Penney WalMart Another business? (Y) Please enter the name of a business: (Merlin Muffler)…
- Use C Language Write a program that reads two matrices of integers. It then generates the sum and difference of the two matrices. The sum of the two matrices of the same size is a matrix with elements that are the sums of the corresponding elements of the two given matrices. Addition is not defined for matrices of different sizes. If A and B are matrices of the same size, then we define subtraction as follows: A – B = A + (-B). Thus, to subtract matrix B from matrix A, we simply subtract corresponding elements.In python. Include docstring. Please follow code requirements as listed below. Write a recursive function named is_subsequence that takes two string parameters and returns True if the first string is a subsequence of the second string, but returns False otherwise. We say that string A is a subsequence of string B if you can derive A by deleting zero or more letters from B without changing the order of the remaining letters. The empty string (which has zero characters) is considered a subsequence of any string (since you can derive it by deleting zero or more letters from any string). You can assume that the only characters in the strings will be lower case letters (though that shouldn't really affect your code). Note: subsequences are different than substrings, since the characters of a subsequence don't have to be consecutive. For example, 'aeiou' is a subsequence of 'faceitious', since all the characters appear in the same order, even though they're not consecutive. You may use…IN C PROGRAMMING LANGUAGE AND COMMENT EVERY STEP PLEASE Write a program that takes verbs and forms their past tense on the basis of these rules: a. If verb ends in “e”, add “d”. b. If verb ends in “ss” or “gh”, add “ed”. c. In all other cases, inform the user that the verb may have an irregular past tense. Print each verb and its past tense. Try the following data: smile discuss confess declare laugh run cough teach buy
- Write a C++ program that prompts the user for 3 values: the half life of an element, the starting quantity, and the target remaining quantity. For the purposes of this program, don't worry about the units of these values. Print out a table with 3 columns: time elapsed, quantity remaining, and percentage of original quantity remaining. Starting when time elapsed = 0, print rows at every half life until the quantity remaining is equal to or less than the target remaining quantity. Finally, print out a message to let the user know how much time needs to elapse to reach the target remaining quantity. All numbers should be printed with at most 2 places after the decimal pointGiven the month and the year, you are required to print the Georgian Calendar' for that month. For example, the calendar for the month of September 2017 is: SM T W T FS 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 The solution to this problem can be rather complex, so we will use functional abstraction to break it down into smaller parts. You are advised to implement and test each part (by defining a suitable main function) before moving on the the next part. You are to implement the following functions: 1. bool is leap_year(int year) to determine if a given year is leap. Note that not all years which are multiples of 4 are leap. Centuries are not leap unless they are multiples of 400. 2. int days_in_month(int month, int year) that takes the month (an integer from 1 to 12) and year, and returns number of days in the given month (an integer from 1 to 31). Note that you should use the is_leap_year function to determine if February has 28 or 29 days.…3, A lecturer intends to separate his students into 2 groups based on their INDEX Numbers, those with odd numbers in group A and EVEN numbers in B.
