问题描写叙述: 给定数组,找出连续乘积最大值的子序列.比如 0,-1,-3.-2.则最大连续乘积为6= (-3) * (-2) 实现思路此题与最大连续和的子序列问题相似,也可通过找到递推公式然后用DP来解.关键在于求公式的过程要考虑到元素可能为负的情况.如果元素都为正数的话,DP公式为:dp[i] = max(a[i],dp[i-1]*a[i]) ,乘或不乘,取最大的那个可元素可能为负数.因此能够使用min和max分别存当前最大值和最小值,如果当前元素为负数的话,当前最小值就成了最大值.这样一来…

题目大意: 连续最大子段积 题目思路: 最大值只能产生在一个正数x一个正数,一个负数乘一个负数,所以维护两个值,一个区间最大值,一个最小值 其他的话: 在讨论这个问题之前,我先来说一说大一刚开学就学了的最简单的dp问题之一的[最大连续子序列] 先来看一个数组a{ -2, 11, -4, 13, -5, -2 },求连续子序列中和最大的那个 对于第i个数来说,dp[i]表示,以i结尾的序列最大的和为dp[i] 状态转移方程为dp[i] = max{ dp[i-1] + a[i], a[i] } 无…
