Given a triangle field and a rope of a certain length (Figure-1), you are required to use the rope to enclose a region within the field and make the region as large as possible. Input The input has several sets of test data. Each set is one line cont…
Given a triangle, find the minimum path sum from top to bottom. Each step you may move to adjacent numbers on the row below. For example, given the following triangle [ [], [,4], [6,,7], [4,,8,3] ] The minimum path sum from top to bottom is 11 (i.e.,…

Given a triangle, find the minimum path sum from top to bottom. Each step you may move to adjacent numbers on the row below. For example, given the following triangle [ [], [,4], [6,,7], [4,,8,3] ] 一开始的题目的意思理解错了 ,以为是位数相差一就是临近的意思,但实际上这里意思是图形上面的那种临近,和原…
就是暴力枚举a, b然后和题目给的数据比较就ok了. 刘汝佳这道题的讲解有点迷,书上讲有x1和a可以算出x2, 但是很明显x2 = (a * x1 +b) 没有b怎么算x2?然后我就思考了很久,最后去看他的代码发现他的代码和他讲的是两回事 他的代码里直接是枚举a和b,不是按照书上的思路来的. 有点迷 #include<iostream> #define REP(i, a, b) for(int i = (a); i < (b); i++) using namespace std; con…
D Even Parity Input: Standard Input Output: Standard Output We have a grid of size N x N. Each cell of the grid initially contains a zero(0) or a one(1). The parity of a cell is the number of 1s surrounding that cell. A cell is surrounded by at most…
题意:给定一个 n,求一个最大正整数 N 使得 N 的所有正因数和等于 n. 析:对于任何数一个 n,它的所有正因子都是大于等于本身的,因为 n 本身就是自己的正因数,这样的就可以直接暴力了,答案肯定是在 1 ~ n 范围内. 代码如下: #pragma comment(linker, "/STACK:1024000000,1024000000") #include <cstdio> #include <string> #include <cstdlib&…
