Problem Description
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!

Input
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.
It is guarantied that all integers are in the range of 32-int.
Output
For each case, print the sorting result, and one line one case.
Sample Input
23 2 1 39 1 4 7 2 5 8 3 6 9
Sample Output
1 2 31 2 3 4 5 6 7 8 9

基础题。(排序)
解题思路:
使用快速排序对数组进行排序。
注意输出格式,最后一个数字后是没有空格的。
Qsort函数可参考:qsort函数
代码:
#include<stdio.h>int comp(const void *a,const void *b){return *(int *)a-*(int *)b;}main(){ int i,n,t; int s[1001]; scanf("%d",&n); while(n--) { scanf("%d",&t); for(i=0;i<t;i++) { scanf("%d",&s[i]); } qsort(s,t,sizeof(int),comp); for(i=0;i<t;i++){ printf("%d",s[i]); if(i!=t-1) printf(" "); } printf("\n"); }}
