Description
find the median of several integers
Input
The first line of input is the number of test cases T(T
#include <stdio.h>
void fun(double a[],int m){
int i,j,temp;
for(i=1;i<m;i++)
for (j=0; j<m-i; j++) {
if(a[j]>a[j+1]){
temp = a[j];
a[j] = a[j+1];
a[j+1] = temp;
}
}
}//冒泡排序
int main(){
int n,m,i;
double a[111];
double ave;
while (~scanf("%d",&n)) {
while (n--) {
scanf("%d",&m);
for(i=0;i<m;i++){
scanf("%lf",&a[i]);
}
fun(a,m);
if(m%2==1){
ave=a[m/2];
}//是奇数
else{
ave=(a[m/2]+a[m/2-1])/2;
}//是偶数
if(int(ave)*1.0==ave)
printf("%d\n",(int)ave);//是整数
else
printf("%.1lf\n",ave);//是小数
}
}
}
