Description
Score : $250$ points
Problem Statement
You are trying to implement collision detection in a 3D game.
In a $3$-dimensional space, let $C(a,b,c,d,e,f)$ denote the cuboid with a diagonal connecting $(a,b,c)$ and $(d,e,f)$, and with all faces parallel to the $xy$-plane, $yz$-plane, or $zx$-plane.
(This definition uniquely determines $C(a,b,c,d,e,f)$.)
Given two cuboids $C(a,b,c,d,e,f)$ and $C(g,h,i,j,k,l)$, determine whether their intersection has a positive volume.
Constraints
- $0 \leq a < d \leq 1000$
- $0 \leq b < e \leq 1000$
- $0 \leq c < f \leq 1000$
- $0 \leq g < j \leq 1000$
- $0 \leq h < k \leq 1000$
- $0 \leq i < l \leq 1000$
- All input values are integers.
Input
The input is given from Standard Input in the following format:
$a$ $b$ $c$ $d$ $e$ $f$ $g$ $h$ $i$ $j$ $k$ $l$
Output
Print Yes if the intersection of the two cuboids has a positive volume, and No otherwise.

问题陈述
你正在尝试在3D游戏中实现碰撞检测。
在三维空间中，记$C(a,b,c,d,e,f)$为一个以$(a,b,c)$和$(d,e,f)$为对角线的长方体，且所有的面都平行于$xy$-平面、$yz$-平面或$zx$-平面。
（这个定义唯一确定了$C(a,b,c,d,e,f)$。）
给定两个长方体$C(a,b,c,d,e,f)$和$C(g,h,i,j,k,l)$，判断它们的交集是否具有正体积。
约束条件
- $0 \leq a < d \leq 1000$
- $0 \leq b < e \leq 1000$
- $0 \leq c < f \leq 1000$
- $0 \leq g < j \leq 1000$
- $0 \leq h < k \leq 1000$
- $0 \leq i < l \leq 1000$
- 所有输入值都是整数。
输入
输入从标准输入以以下格式给出：
$a$ $b$ $c$ $d$ $e$ $f$ $g$ $h$ $i$ $j$ $k$ $l$
输出
如果两个长方体的交集具有正体积，则打印Yes，否则打印No。
