[NAC 2025] Solar Farm

题目描述

You are building a new solar farm. The area in which you are allowed to build is a circular field of radius rr, and the solar panels each take up a rectangular space of size w×hw \times h. You must place all the panels in the same orientation of your choice in a single rectangular array (so that all of the panels combined exactly form a single rectangle). What is the maximum number of panels that you can fit in this farm?

输入格式

The first line of input contains a single integer TT (1T10001\leq T \leq 1\,000). This is the number of test cases.

The next TT lines of input each represent one test case and consist of three space-separated integers rr, ww, and hh (1r,w,h1091 \leq r, w, h \leq 10^9): the radius of the field, the width of each solar panel, and the height of each solar panel, respectively.

输出格式

For each test case, print a line with a single integer: the maximum number of solar panels that can be placed in a solar farm within the circular field.
