题目描述: Yogurt factory The cows have purchased a yogurt factory that makes world-famous Yucky Yogurt. Over the next N (1 <= N <= 10,000) weeks, the price of milk and labor will fluctuate weekly such that it will cost the company C_i (1 <= C_i <=…
2014-04-29 04:36 题目:最大子数组和的二位扩展:最大子矩阵和. 解法:一个维度上进行枚举,复杂度O(n^2):另一个维度执行最大子数组和算法,复杂度O(n).总体时间复杂度为O(n^3),还需要O(n)额外空间. 代码: // 18.12 Given an n x n matrix, find the submatrix with largest sum. Return the sum as the result. #include <algorithm> #include &…
2014-04-29 00:04 题目:给定一个整数数组,找出所有加起来为指定和的数对. 解法1:可以用哈希表保存数组元素,做到O(n)时间的算法. 代码: // 17.12 Given an array of integers and target value, find all pairs in the array that sum up to the target. // Use hash to achieve O(n) time complexity. Duplicates pairs…
--------------------------------------------- 这道题有点坑,也怪我总是有点马虎,按照正常人的思维0是表示有水池啊竟然是1表示有水池,最坑的是写反了竟然还能过样例一直以为是自己程序问题review了好多遍.... 图论基础题,染色法即可. AC代码: import java.util.Scanner; public class Main { public static void main(String[] args) { Scanner sc=new…
-------------------------------------祭出BigInteger AC代码: import java.math.BigInteger; import java.util.Scanner; public class Main { public static void main(String[] args) { Scanner sc=new Scanner(System.in); int n=sc.nextInt(); BigInteger ans=fac(n);…
