2525. 根据规则将箱子分类

题目描述

给你四个整数 length ，width ，height 和 mass ，分别表示一个箱子的三个维度和质量，请你返回一个表示箱子 类别 的字符串。

  • 如果满足以下条件，那么箱子是 "Bulky" 的：
    • 箱子 至少有一个 维度大于等于 104 。
    • 或者箱子的 体积 大于等于 109 。
  • 如果箱子的质量大于等于 100 ，那么箱子是 "Heavy" 的。
  • 如果箱子同时是 "Bulky" 和 "Heavy" ，那么返回类别为 "Both" 。
  • 如果箱子既不是 "Bulky" ，也不是 "Heavy" ，那么返回类别为 "Neither" 。
  • 如果箱子是 "Bulky" 但不是 "Heavy" ，那么返回类别为 "Bulky" 。
  • 如果箱子是 "Heavy" 但不是 "Bulky" ，那么返回类别为 "Heavy" 。

注意，箱子的体积等于箱子的长度、宽度和高度的乘积。

 

示例 1：

输入：length = 1000, width = 35, height = 700, mass = 300
输出："Heavy"
解释：
箱子没有任何维度大于等于 104 。
体积为 24500000 <= 109 。所以不能归类为 "Bulky" 。
但是质量 >= 100 ，所以箱子是 "Heavy" 的。
由于箱子不是 "Bulky" 但是是 "Heavy" ，所以我们返回 "Heavy" 。

示例 2：

输入：length = 200, width = 50, height = 800, mass = 50
输出："Neither"
解释：
箱子没有任何维度大于等于 104 。
体积为 8 * 106 <= 109 。所以不能归类为 "Bulky" 。
质量小于 100 ，所以不能归类为 "Heavy" 。
由于不属于上述两者任何一类，所以我们返回 "Neither" 。

 

提示：

  • 1 <= length, width, height <= 105
  • 1 <= mass <= 103

解法

方法一：模拟

根据题意模拟即可。

时间复杂度 $O(1)$，空间复杂度 $O(1)$。
