题目链接:http://poj.org/problem?id=1579 思路分析:题目给出递归公式,使用动态规划的记忆搜索即可解决. 代码如下: #include <stdio.h> #include <string.h> + ; int dp[MAX_N][MAX_N][MAX_N]; int w( int a, int b, int c ) { ) return dp[a][b][c]; || b <= || c <= ) ; else if ( a < b…
典型的记忆化递归问题. 这类问题的记忆主要是利用数组记忆.那么已经计算过的值就能够直接返回.不须要进一步递归了. 注意:下标越界.递归顺序不能错,及时推断是否已经计算过值了,不要多递归. 或者直接使用动态规划法填好表也是能够的. #include <stdio.h> #include <limits.h> const int MAX_N = 21; int W[MAX_N][MAX_N][MAX_N]; int getValue(int a, int b, int c) { if…
