我工作的一个项目涉及动态规划和我打这个微不足道的小事，请大家帮帮忙。

I am working on a project involving "Dynamic Programming" and am struck on this trivial thing, please help.

假如我拿4作为输入，我想显示是这样的：0000 1111

Suppose I take 4 as an input, I want to display something like: 0000 to 1111

但是，如果我输入5，我想要显示像：00000到11111等等

But, if I input 5, I want to display like: 00000 to 11111 and so on.

在此先感谢，

修改：请不要发布问我为code。这不是一个家庭作业问题，我不需要任何code，只是告诉我的逻辑是，我会很高兴。

EDIT: Please don't post asking me for the code. This is not a homework problem and I don't need any code, just tell me the logic for it and I would be happy.

EDIT2 ：WTH正在发生的事情＃1，我没有问任何你写code给我吗？我想谁downvoted到upvote它的人。什么是点这个论坛，如果我不能帮忙？

EDIT2: WTH is happening with Stackoverflow, did I ask any of you to write code for me? I want the person who downvoted to upvote it. What is a point of this forum if I can't for help?

与我分享的逻辑。我们可以讨论，我不需要code这一点。

Share the logic with me. We can discuss and I do not require the code for this.

EDIT3 ：在这里，我张贴了code，我试过了。我希望这个满足所有谁在想我还没有尝试过任何人。

EDIT3: Here I am posting the code which I tried. I hope this "SATISFIES" all the people who were thinking I have not tried anything.

import java.util.ArrayList;

公共类RegularInvestigator {

public class RegularInvestigator {

公开的ArrayList createCombinations（ArrayList中listOfFlightNumbers）{

public ArrayList createCombinations(ArrayList listOfFlightNumbers) {

ArrayList<String> result = new ArrayList<String>();

for(int i = 1; i < listOfFlightNumbers.size(); i++) {

  String binaryEqvivalent = Integer.toBinaryString(i);System.out.println(binaryEqvivalent);
  String element = "";

  for(int j = 0; j < binaryEqvivalent.length(); j++)
    if(binaryEqvivalent.charAt(j) == '1')
      element += listOfFlightNumbers + " ";

  result.add(element.substring(0, element.length() - 1));
}

return result;

}

private String getContent(ArrayList<String> flight) {
String temp = "";

for(int i = 0; i < flight.size() - 1; i++)  temp += flight.get(i) + " ";

temp += flight.get(flight.size() - 1);

return temp;

}

私人的ArrayList removeElementAtIndex（ArrayList中飞行，INT位置）{

private ArrayList removeElementAtIndex(ArrayList flight, int position) {

ArrayList<String> res = new ArrayList<String>();

for(int i = 0; i < flight.size(); i++) {
  if(i != position) res.add(flight.get(i));
}

return res;

} }

EDIT4 ：谢谢phoxis，PengOne，杰里棺材oliholz​​您的宝贵答案：）

EDIT4: Thank you phoxis, PengOne, Jerry Coffin and oliholz for your valuable answers :)

推荐答案

Get input n Count from i=0 to (2^n) - 1 for each value of i bitmask each bit of i and display.
