Question 1(b)You are in an office to meet a friend. Your friend has given you his room number and asked you to go directly to his room when you arrivewithout giving him any call. Now, you are looking for someone who can help you locate the room, but you find everyone is super busy. On a screen, youfind that each room number itself explains where the room is located. There are 12 floors on the building, each having two wings: North and South, andeach wing has 20 rooms. The ground floor doesn't have any room, it is an open lobby (so the topmost floor is the 11th floor). An example of a roomnumber is 'RNO7S12', which means that the room is the 12th room of the South wing on the 7th floor. More examples: RN11N20, RN01S01, RNO9N17,etc. Write a regular expression for such room numbers.

Answered: You are in an office to meet a friend.…

Suppose you always eat a particular brand of cookies out of the standard-sized package it comes in from the store, which has 4 rows of cookies in equal amounts. You notice that when you eat 3 at a time, there's always one cookie left over. you decide when you purchase the next package, you'll eat 5 at a time but still, there's always one cookie left over. Since it really isn't helpful to always have a leftover cookie you decide to eat 7 at a time and there are no cookies leftover, but you do notice that in your last grab of 7 cookies, you're one cookie short
For this milestone, you will be creating a much more complex drawing for each cell and individually filling them in. The drawing will have 4 different sections that can be individually filled in. Then create a grid using the drawing, similar to milestone 3. Once again, we will be adding inputs for 4 new colors. Sample output: Grid size (n): (input) Pen color: (input) Color 1: (input) Color 2: (input) Color 3: (input) Color 4: (input) You can still: decide whether the cells and its drawings are filled or unfilled and decide where Colors 1-4 go in your drawing choose the fill and pen colors based on user input Once again, you'll be trying to match the drawing provided:
Please read requirement carefully. DO NOT COPY AND PASTE FROM OTHER SOLUTION AVAILABLE ONLINE There are two players adding words to a growing word fragment. Each player will take turns attempting to add letters to a growing word fragment. The letter you select should attempt to force your opponent to spell a word or create a word fragment that has no possibility of creating a word. Unlike the prior ghost competition, when it is your turn you are allowed to add a letter to either the front or back of the word fragment.Winning Criteria:If your opponent spells a word that is at least 6 characters longif your opponent creates a word fragment that has no possibility of creating a wordif your opponent takes longer than 60 seconds to select a word.Tip: If you are the first player you can only spell words that are odd length thus you can only lose when you spell words that are odd but you can win when your opponent spells words that are even length. Accordingly, if you are the first player you…
You will required to design a digital clock/chronometer and alarm in this assignment. You will use an alphanumeric LCD display to show the clock (@first line) and the chronometer (@second line). The clock should show hour (24 hour format), minute and second. Choronometer will have minute: second:milisecond areas. Both of them, clock and chonometer will work continiously. You need give the initial value of them from your embedded software. The alarm clock should also be adjusted from the software. Once it is adjusted, alarm clock value cannot be changed. If alarm is occured during the operation, you should show "ALARM!" string on the display for 10 secs. (@third line)
Instructions This assignment uses the logic from the recent quiz and assignment. You can see some of that code in there.What is different? The sequence of operations, spending and finding money, is totally controllable with buttons.This makes the program very flexible. Update the Code below with the following: Add 2 new event functions: buyTortilla() and addFoundMoney(). Add 2 new buttons that trigger buyTortilla() and addFoundMoney().

Using DrawingPanel.java (from chapter 3G), draw a grid for filling in a 4 x 4 square of cell containing integers. For this part of the assignment the values are not important, but you are welcome to use the values shown in the magic square from below. Note that the values in any horizontal row, vertical column or main diagonals add up to 34, in addition to various sub-squares in the larger square also add up to the same value. Requirements: The magic square should be centered in the panel The values in each of the cells should be centered in that cell (both horizontally and vertically). You can assume the values will be <= 99 (i.e., at most 2 digits). For this part of the assignment, you can hard-code the values; you will store them in a 2-dimensional array (from chapter 7) when implementing Part B of the assignment. The title "CSC 142 Magic Square" is centered horizontally in the panel and at y = 50 You are free to choose the colors, fonts, font sizes and effects. This is what I used…
