题意描述: Vova先生的家可以看作一个n×1的矩形,寒冷的冬天来了,Vova先生想让他的家里变得暖和起来.现在我们给你Vova先生家的平面图,其中111表示这个地方是加热炉,0表示这个地方什么也没有.所有加热器都有一个加热半径r,一个位于ai加热器可以加热[ai−r+1,ai+r−1]的范围.现在,Vova先生想让他的整个家都变得暖和,一开始所有的加热器都是关闭的,请你求出Vova先生最少要开几个加热器才能使整个家变得暖和 输入输出格式: 输入格式: 第一行:两个整数n,r(1≤n,r≤100…

思路: 从左向右贪心选择能覆盖当前位置的最靠右的那个heater即可,和poj radar installation类似. 实现: #include <iostream> #include <cassert> using namespace std; const int INF = 0x3f3f3f3f; ], cov[]; int main() { int n, r; while (cin >> n >> r) { fill(cov + , cov + n…

Winter is coming! Your first job during the contest is to design a standard heater with fixed warm radius to warm all the houses. Now, you are given positions of houses and heaters on a horizontal line, find out minimum radius of heaters so that all…

https://leetcode.com/problems/heaters/ 开始的时候,下面的代码对于两边数字完全一样的情况,测试不通过.原因是heater会有重复情况,这时候对于飘红部分就不会往前面继续检查.所以把<改成<=让相同的情况也继续往前面走,走到最后一个,就可以了.Accepted! package com.company; import java.util.Arrays; class Solution { public int findRadius(int[] houses,…
