Description The Pizazz Pizzeria prides itself in delivering pizzas to its customers as fast as possible. Unfortunately, due to cutbacks, they can afford to hire only one driver to do the deliveries. He will wait for 1 or more (up to 10) orders to be
题意大概就是,给定一个包含非负整数的序列nums以及一个整数m,要求把序列nums分成m份,并且要让这m个子序列各自的和的最大值最小(minimize the largest sum among these m subarrays). Note:If n is the length of array, assume the following constraints are satisfied: 1 ≤ n ≤ 10001 ≤ m ≤ min(50, n) Examples: Input:num
假设关键字的总数为n,用c[i,j]表示第i个关键字到第j个关键字的最优二叉查找树的代价,我们的目标是求c[0,n-1].要求c[i,j],首先要从第i个关键字到第j个关键字中选一个出来作为根结点,选出根结点后,最优二叉搜索树的代价为左子树的代价加上右子树的代价,由于每选出一个根结点,每个关键字的搜索长度都增加1,因此得出递推式,即当 package org.xiu68.ch06.ex6; public class Ex6_20 { //动态规划,最优二叉搜索树 public static vo
