删除重复的行 [英] Removing repeated rows

问题描述

我想删除数字组合中重复的行。

我已经发布了代码。请运行，看看。

提前感谢



我的尝试：

i want to remove the repeated rows in the combinations of numbers.
i have posted code for that. please run that and see.
thanks in advance

What I have tried:

#include<stdio.h>

int main()
{
	int arr[9] = {1, 2, 3, 4, 5, 6, 7, 8, 9};
	
	int i,j=9,x;
	while(j>0) 
	{
    	for (i=1; i<9; i++) 
    	{   
			for(x=0;x<9;x++)
			{
        		if (x!= j&&x!=i) 
				{
					printf("%d",arr[x]);
				}	
        		else 
				{
					printf("*");
				}    
			}
			printf("\n");

    	}
		j--;
		printf("\n");
	}
	return 0;
}

推荐答案

这听起来像是我的作业...



我会给你一个提示：在创建组合时，将它们存储在一个新的数组中。然后你有一个你已经创建的内容的参考，可以比较以确定它是否是一个独特的组合。

This sounds like homework to me...

I'll give you a tip: As you create your combinations, store them in a new array. Then you have a reference of what you have already created and can compare against to determine whether it is a unique combination or not.

- 优化删除重复行的定义，因为这不是你的代码。

显示你想要的输出和输出的例子。



- 您是否注意到您的阵列没有重复行？

要测试删除重复行的程序，最好是拥有重复行的数据样本。



- 在程序中每个位置都硬编码数组的大小是一个坏主意，因为每次你改变大小数组，你必须在每个地方改变代码。用它来存储变量中的大小。

- Refine definition of "remove the repeated rows", as this is not what is doing your code.
Show example of output you want and output you get.

- Did you noticed that your array do not have "repeated rows"?
To test a program that "remove the repeated rows", it is a good idea to have data sample that have "repeated rows".

- Having the size of array hardcoded every where in program is a bad idea, because every time you change the size of array, you have to change code every where. Usage it to store the size in a variable.
