题目描述
Nikhil has some boxes and balls. He now wonders how large a ball he can fit in a given box. Given the dimensions of a box, help Nikhil determine the radius of the largest ball that he can fit in the box. Assume that an inflated ball will be spherical.
Input:-
The first line of the input will be T, the number of test cases. Next follows T lines each containing three space separated integers (L, B, H) which are the length, breadth and height of the box respectively.
Output:-
Print T lines each consisting of the radius(correct to 1 decimal place) of the largest ball that Nikhil can fit in the box of dimensions corresponding to each test case.
Constraints:
1 ≤ T ≤ 10^5
1 ≤ L, B, H ≤ 10^18
