There are some students in a class, Can you help teacher find the highest student .
Input
There are some cases. The first line contains an integer t, indicate the cases; Each case have an integer n ( 1 ≤ n ≤ 100 ) , followed n students’ height.
Output
For each case output the highest height, the height to two decimal plases;
Sample Input
2
3 170.00 165.00 180.00
4 165.00 182.00 172.00 160.00
Sample Output
180.00
182.00
代码:

using namespace std;
double a[105];
bool cmp(double b,double c){
return b>c;
}
int main(void){
int t;
scanf("%d",&t);
while(t--){
int n;
scanf("%d",&n);
for(int i=0;i<n;i++){
scanf("%lf",&a[i]);
}
sort(a,a+n,cmp);
printf("%.2lf\n",a[0]);
}
return 0;
