Web关键是内循环中为什么是逆序的呢,因为要记算当前状态的dp[j],需要的是前一状态的dp[j](即dp [j-1]),而逆序循环时前面的一定就是前一状态的dp[j],可以直接拿来用,而正序循环之所以不可以,是因为当你计算完前面的dp[j]时,dp[j-1]存的就不是i-1时刻的值了,而你后面还要用dp[j-1]。 Web12 apr 2024 · 1.首先定义一个状态转移数组dp,dp [i] [j]表示前i件物品放入容量为j的背包中所能得到的最大价值;. 2.寻找数组元素之间的关系式,也就是状态转移方程,我们将第i件物品是否放入背包中这个子问题拿出来进行分析,首先要明确的是我们的一切目标都是使得在既有 ...
