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.)

- Help Me With C Programming. At Lili's birthday party, there is a game arranged by Jojo as the host. The game is handing out a number of Y candies to a number of X people where all the sweets taste sweet except for the last one candy that tastes like rotten beans. The distribution of sweets will be sequential starting from position Z and if it passes the last position then the distribution of candy continues to the first position. Write down the person in the position of who will get the last candy. Format Input The first line of input is T, which is the number of test cases. The second row and the next number of T lines are X, Y, Z. X is the number of people who will be handed out candy. Y is the number of candies available. Z is the initial position of the person who will be handed out the candy. Format Output A string of "Case #N: " and a number that is the position of the person who got the last candy [Look at Image] In the sample above, for example, which is inputted in the…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…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/
- Please complete this program in C++ Please enusre that there is plenty of comments. PLENTY even if unessessary. Please include screenshots of actual code, screenshots of output, and code in the browser so I can copy and paste. Thank you.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.Use C Language Write a program that reads two matrices of integers.

- 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…Please help with this c++ problem Assignment 6 - Monkey Food In the Gaddis textbook read Chapter 8 sections 8.1-8.9 before starting this assignment. This assignment is Programming Challenge 4 from Chapter 8 of the textbook. A local zoo wants to keep track of how many pounds of food each of its three monkeys eats each day during a typical week. Write a program that stores this information in a two-dimensional 3 x 7 arrray, where each row represents a different monkey and each column represents a different day of the week. The program should first have the user input the data for each monkey from the keyboard. The number of pounds of food eaten by one monkey in one day should be a floating-point value. Input Validation: Do not accept negative numbers. Then your program should create a report that includes the following information: A nicely-formatted table with a row for each monkey and a column for each day of the week showing the amount of food eaten by that monkey on that day. Be…When the robot makes a turn, it would be useful to have an operation to perform on d to represent this turn. This is because after making a turn, the new value of d will depend on the old value of d. Complete the table for the new values of d if the robot is turning left or right.Then determine an expression in terms of d that will give the new position if the robot turns left and another expression if the robot turns right. Type these expressions in the last row of the table. Attached is the table I completed. All rows are correct except the last one. I'm not sure what my error is.
- Given 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.…Recursive Palindrome! Recall that a palindrome is a string that reads the same forward and backward. Write a recursive function is_palindrome (s:str) -> bool to check whether a string s is a palindrome. Here's a hint: think about how you can use is_palindrome(t), where t is a substring of s, to help you decide whether s is a palindrome.
