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
