c# - 文字轰炸

Question

这是我正在尝试编写的程序:

Write a program that reads a text and line width from the console. The program should distribute the text so that it fits in a table with a specific line width. Each cell should contain only 1 character. It should then read a line with numbers, holding the columns that should be bombarded.

我的代码是这样的:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace _04.Text_Bombardment
{
    class Program
    {
        static void Main(string[] args)
        {
            var sentence = Console.ReadLine();
            var bombing = int.Parse(Console.ReadLine());
            var selected = Console.ReadLine().Split(' ').Select(int.Parse).ToArray();
            Dictionary<int, bool> bombDict = new Dictionary<int, bool>();
            var newSentence = sentence + new string(' ', bombing - sentence.Length % bombing); // whole row minus words left

            for (int i = 0; i < selected.Length; i++)
            {
                bombDict.Add(selected[i], true);
            }
            var rows = newSentence.Length / bombing;
            var cols = bombing;

            var count = 0;

            var arrSent = newSentence.ToCharArray();
            for (int i = 0; i < rows; i++)
            {
                for (int j = 0; j < cols; j++)
                {
                    if (bombDict.ContainsKey(j) && bombDict[j] == true && arrSent[count] != ' ')
                    {
                        arrSent[count] = ' ';
                        try
                        {
                            if (arrSent[count + bombing] == ' ')
                            {
                                bombDict[j] = false;
                            }
                            else
                            {
                                bombDict[j] = true;
                            }

                        }
                        catch (IndexOutOfRangeException)
                        {
                            continue;
                        }
                   }
                   count++;
                }
            }
            var finalSent = string.Join("", arrSent).TrimEnd();
            Console.WriteLine(finalSent);
       }
   }
}

它在这句话上中断了:

Vazov received his elementary education in hisnative town of Sopoandat Plovdiv. The son of a conservative, well-to-do merchant.
20
1 6 17 2 5 0 15

当前输出:

ov  eceived  i  e   en  ry educa i n    hi  ative to n of  opo  dat Plov iv. T e s   of a co serva ive  well-to- o mer ha t.

预期输出:

ov  eceived  i  e   en  ry educa i n    hi  ative to n of  opo  dat Plov iv. T e s   of a co serva ive  well-to- o mer han . 

所以它只在最后不起作用。有人能帮我吗？有什么建议吗？

补充说明:

^{例如，我们阅读文本“Well this problem is gonna be a ride.”和线宽 10。我们将文本分布在 4 行 10 列中。我们读取数字“1 3 7 9”并在表中的这些列上投下炸弹。炸弹摧毁了它们落在的角色及其下方的所有相邻角色。
注意:被摧毁角色下方的空白区域可以阻止炸弹(见第 7 栏)。最后，我们在控制台上打印轰炸文本:“W l th s o lem i o na be a r de。”注意:不应打印表格中文本后的空单元格。}

您的解决方案很难理解，请保持简单，为您可以轻松理解的变量命名。

我修改了你的代码，希望对你有帮助:

static void Main()
{
    string sentence = "Well this problem is gonna be a ride.";
    int numberOfColumns = int.Parse("10");
    List<int> bombs = "1 3 7 9".Split(' ').Select(int.Parse).ToList();


    // we need to convert to decimal, otherwise C# will ignore decimal part. 
    //example: 127/20 = 6.35, so we need 7 rows. if we don't convert to decimal we have 6
    // the Ceiling says, always round up. so even 6.1 will be rounded to 7
    int numberOfRows = (int)Math.Ceiling(sentence.Length / Convert.ToDecimal(numberOfColumns));

    char[,] array = new char[numberOfRows, numberOfColumns];

    int sentencePointer = 0;
    for (int rowIndex = 0; rowIndex < numberOfRows; rowIndex++)
    {
        for (int colIndex = 0; colIndex < numberOfColumns; colIndex++)
        {
            // if you want to print the grid with the full text, just comment the 3 lines below,
            //and keep only "array[rowIndex, colIndex] = sentence[sentencePointer];"
            if (bombs.Contains(colIndex))
            {
                if (sentence[sentencePointer] == ' ') // bomb is deactivated
                {
                    bombs.Remove(colIndex);
                    array[rowIndex, colIndex] = sentence[sentencePointer];
                }
                else
                    array[rowIndex, colIndex] = '*'; // * represents a bomb
            }
            else
                array[rowIndex, colIndex] = sentence[sentencePointer];

            sentencePointer++; // move next character
            if (sentencePointer >= sentence.Length)
                break; // we reach the end of the sentence.
        }
    }

    PrintGrid(array, numberOfRows, numberOfColumns);

    // just give some space to print the final sentence
    Console.WriteLine("");
    Console.WriteLine("");
    Console.WriteLine("");

    for (int rowIndex = 0; rowIndex < numberOfRows; rowIndex++)
    {
        for (int colIndex = 0; colIndex < numberOfColumns; colIndex++)
        {
            Console.Write(array[rowIndex, colIndex]);
        }
    }

    Console.ReadKey();
}

private static void PrintGrid(char[,] array, int numberOfRows, int numberOfColumns)
{
    Console.WriteLine(new string('-', numberOfColumns * 2));

    for (int rowIndex = 0; rowIndex < numberOfRows; rowIndex++)
    {
        Console.Write("|");
        for (int colIndex = 0; colIndex < numberOfColumns; colIndex++)
        {
            Console.Write(array[rowIndex, colIndex]);
            Console.Write("|");
        }
        Console.WriteLine("");
    }
}
