Here's an example of HTML/CSS code that aligns an image vertically in a division that spans vertically on the whole webpage: HTML: ``` <body> <div class="vertical-container"> <img src="your-image.jpg" alt="Your Image"> </div> </body> ``` CSS: ``` body { margin: 0; padding: 0; } .vertical-container { height: 100vh; /* sets the height of the container to 100% of the viewport height */ display: flex; justify-content: center; /* centers the image horizontally */ align-items: center; /* centers the image vertically */ } .vertical-container img { max-width: 100%; /* ensures the image doesn't exceed the width of the container */ max-height: 100%; /* ensures the image doesn't exceed the height of the container */ } ``` In this example, we create a `div` element with a class of `vertical-container` and an `img` element inside it. We use CSS to set the height of the `div` to `100vh`, which sets the height of the container to 100% of the viewport height. We then use `display: flex` to make the container a flex container and `justify-content: center` and `align-items: center` to center the image both horizontally and vertically within the container. Finally, we use `max-width: 100%` and `max-height: 100%` on the `img` element to ensure that the image doesn't exceed the width or height of the container. This code will align the image vertically in the division that spans vertically on the whole webpage.

Robert is a famous engineer. One day he was given a task by his boss. The background of the task was the following: Given a map consisting of square blocks. There were three kinds of blocks: Wall, Grass, and Empty. His boss wanted to place as many robots as possible in the map. Each robot held a laser weapon which could shoot to four directions (north, east, south, west) simultaneously. A robot had to stay at the block where it was initially placed all the time and to keep firing all the time. The laser beams certainly could pass the grid of Grass, but could not pass the grid of Wall. A robot could only be placed in an Empty block. Surely the boss would not want to see one robot hurting another. In other words, two robots must not be placed in one line (horizontally or vertically) unless there is a Wall between them. Now that you are such a smart programmer and one of Robert's best friends, He is asking you to help him solving this problem. That is, given the description of a map, compute the maximum number of robots that can be placed in the map. Input The first line contains an integer T (<= 11) which is the number of test cases. For each test case, the first line contains two integers m and n (1<= m, n <=50) which are the row and column sizes of the map. Then m lines follow, each contains n characters of '#', '', or 'o' which represent Wall, Grass, and Empty, respectively. Output For each test case, first output the case number in one line, in the format: "Case :id" where id is the test case number, counting from 1. In the second line just output the maximum number of robots that can be placed in that map.

To solve it, we can use a simple algorithm that iterates over all empty cells in the map and checks whether a robot can be placed there. For each empty cell, we can simulate a robot firing its laser ...

c++Bessie and friends have been captured and are trapped in a secret compound in a location far from their farm, and it is up to Bessie to plan their escape! The compound consists of � � NK holding cells arranged in an � × � N×K rectangular grid, where there are gates between horizontally and vertically adjacent cells. Each cell houses exactly one cow. Bessie has hacked into the system, and is able to unlock any subset of the gates, but each gate has a cost. For the cows to escape, Bessie must open enough gates that all the cows can gather in a single cell (so that they have enough cow-power to tunnel to the surface!). Bessie wants to minimize the total unlocking cost. But the stakes are higher than ever, and Bessie cannot be content with just one escape plan: she needs back-ups. Help her count the number of minimum-cost escape plans; two plans are considered different if some gate needs to be unlocked in one of the plans but not the other. Since this number may be very large, only output its remainder modulo 1 0 9 + 7 10 9 +7.

A random number of Rabbit images ranging from 1 to 10 are displayed for each operand and the user is expected to enter the values of the two operands and the result of adding the two operands, in the given text fields. When the user clicks on the button ‘Check!’, one of two things can happen: Case 1: all three input values are correct i) the text changes to ‘"Correct! Have another go?"’. ii) the number of Rabbit images displayed for each of the two operands changes. See Figure 2 for an example. iii) the three text fields are reset (i.e. they are made empty). 2/5 Case 2: at least one of the input values entered is incorrect i) the text changes to ‘Wrong! Try again!’. ii) the number of Rabbit images displayed does NOT change. iii) the text fields do NOT change.Implement SumItUp as a Java application. You application must satisfy ALL the specific requirements given below: a) The title of the top-level container must be ‘Welcome to SumItUp!’. b) The initial text should be ‘Enter two operands, result and click on 'Check!'’. See Figure 1. c) There should be no more than 4 Rabbit images per row. See Hint 1. d) The text fields should be wide enough to display at least TWO characters. e) The button ‘Check!’ must not resize when the GUI is resized. See Hint 2 and Figure 3. f) The ‘plus sign’ icon should appear vertically centered between the two sets of Rabbit images and must not resize when the GUI is resized. See Hint 2 and Figure 3. g) When first launched and whenever a correct answer is given, the number of displayed Rabbit images for each operand should change to any number between 1 and 10 (inclusive). See Hint 3 and Hint 4. Note: It is possible for the next number(s) to be the same as the current number(s). h) Nothing should happen if the user clicks the ‘Check!’ button while at least one of the text fields are empty, i.e. no errors should be thrown in this case. Note: You can assume that only a numeric value will be entered into the text fields.

Note: This code assumes that you have images named "rabbit.png", "plus.png", and "equals.png" in the same directory as your Java source file. If you want to use different images, you'll need to modify...

用C++解决On an 8×8 grid of dots, a word consisting of lowercase Latin letters is written vertically in one column, from top to bottom. What is it? Input The input consists of multiple test cases. The first line of the input contains a single integer t (1≤t≤1000 ) — the number of test cases. Each test case consists of 8 lines, each containing 8 characters. Each character in the grid is either . (representing a dot) or a lowercase Latin letter (a –z ). The word lies entirely in a single column and is continuous from the beginning to the ending (without gaps). See the sample input for better understanding. Output For each test case, output a single line containing the word made up of lowercase Latin letters (a –z ) that is written vertically in one column from top to bottom. Example inputCopy 5 ........ ........ ........ ........ ...i.... ........ ........ ........ ........ .l...... .o...... .s...... .t...... ........ ........ ........ ........ ........ ........ ........ ......t. ......h. ......e. ........ ........ ........ ........ ........ .......g .......a .......m .......e a....... a....... a....... a....... a....... a....... a....... a....... outputCopy i lost the game aaaaaaaa
