The Final Quest

Здравейте, получавам 91/100 и не мога да си намеря грешката.

 

 

 

Create a program that follows given instructions. You will receive a collection of words on a single line, split by a single space. They are not what they are supposed to be, so you have to follow the instructions in order to find the real message. You will be receiving commands. Here are the possible ones:

  • Delete {index} – removes the word after the given index if it is valid.
  • Swap {word1} {word2} – find the given words in the collections if they exist and swap their places.
  • Put {word} {index} – add a word at the previous place {index} before the
    given one, if it is valid. Note: putting at the last index simply appends the word to the end of the list.
  • Sort – you must sort the words in descending order.
  • Replace {word1} {word2} – find the second word {word2} in the collection (if it exists) and replace it with the first word – {word1}.

Follow them until you receive the "Stop" command. After you have successfully followed the instructions, you must print the words on a single line, split by a space.

Input / Constraints

  • On the 1st line, you are going to receive the collection of words, split by a single space – strings
  • On the next lines, you are going to receive commands, until you receive the "Stop" command

Output

  • Print the words you have gathered on a single line, split by a single space

Examples

Input

Output

Congratulations! You last also through the have challenge!

Swap have last

Replace made have

Delete 2

Put it 4

Stop

Congratulations! You made it through the last challenge!

Comments

First, we receive the command “Swap”, so we change the positions of the words have and last. The text at this point should look like this:

Congratulations! You have also through the last challenge!

After that, we receive “Replace” and we have to replace the second word – “have” with the first – “made”. Afterwards we have to delete the word, which is after the second index. And finally, we have to put a word on the previous position before 4.

Input

Output

This the my quest! final

Put is 2

Swap final quest!

Delete 2

Stop

This is the final quest!

Здарвей,

Много сложно си направил put командата.

Може да пробваш така:

                else if (token[0] == "Put")
                {
                    string word = token[1];
                    int index = int.Parse(token[2]) - 1;

                   if (text.Count >= index  && index >= 0)
                    {
                       text.Insert(index, word);
                    }
                }

Ето и друг вариант на решение:
