As Easy As A+B
[align=left]Problem Description[/align]These days, I am thinking about a question, how can I get a problem as easy as A+B? It is fairly difficulty to do such a thing. Of course, I got it after many waking nights.
Give you some integers, your task is to sort these number ascending (升序).
You should know how easy the problem is now!
Good luck!
[align=left]Input[/align]
Input contains multiple test cases. The first line of the input is a single integer T which is the number of test cases. T test cases follow. Each test case contains an integer N (1<=N<=1000 the number
of integers to be sorted) and then N integers follow in the same line.
It is guarantied that all integers are in the range of 32-int.
[align=left]Output[/align]
For each case, print the sorting result, and one line one case.
[align=left]Sample Input[/align]
2
3 2 1 3
9 1 4 7 2 5 8 3 6 9
[align=left]Sample Output[/align]
1 2 3
1 2 3 4 5 6 7 8 9
比较水的一个题,只需用一下快排就行。
代码如下:
#include<stdio.h>
#include<string.h>
#include<stdlib.h>
#define N 1010
int s
;
int cmp(const void *a,const void *b)
{return *(int *)a-*(int *)b;
}
int main()
{int T;
scanf("%d",&T);
while(T--)
{int n,i;
scanf("%d",&n);
memset(s,0,sizeof(s));
for(i=1;i<=n;i++)
scanf("%d",&s[i]);
qsort(s+1,n,sizeof(s[1]),cmp);
for(i=1;i<n;i++)
printf("%d ",s[i]);
printf("%d\n",s[i]);
}
return 0;
}
