Wind velocity also increase with altitude and may cause serious stress for trees,as is made evident by the deformed shapes at high altitude. Wind velocity also (with altitude)increase and may cause serious (for trees)stress ,as is made (by the (defor…

At the upper timberline the trees begin to become twisted and deformed. This is particularly true for trees in the middle and upper latitudes, which tend to attain greater heights on ridges, whereas in the tropics the trees reach their greater height…

Mountains 题面 题意: 选最多的点使得两两看不见. 分析: 分治,solve(l,r)为区间[l,r]的答案.那么如果不选最高点,分治两边即可,选了最高点,那么在最高点看不见的区间里分治. 代码: #include"mountains.h" #include<bits/stdc++.h> using namespace std; ; int y[N]; int f[N][N]; bool Judge(int a,int b,int c) { // a see c…

题目大意: 用一个数组代表群山的高度.高度大的地方代表山峰,小的地方代表山谷.山谷可以容水.假设有一天下了大雨,求群山中总共可以容纳多少水? 如图所示情况,a代表该数组,总共可以容纳5个水. 解题思路: 初步想法可以枚举每一个单位,判断是否能放水.这种做法的复杂度为O(n^2*h)其中h为数组最大值,n为数组的大小.效率较低. 进一步观察发现:由于只有山谷可以存水,假设a[i],a[j]>a[k](i<k<j),那么i,j之间的水量可以直接算出,问题降解为两个子问题:求0到i的存水量和j…

How to solve this HARD issue 1. Problem: A non-empty zero-indexed array A consisting of N integers is given. A peak is an array element which is larger than its neighbours. More precisely, it is an index P such that 0 < P < N − 1 and A[P − 1] < A…
