// uva 10003 Cutting Sticks 区间dp // 经典的区间dp // dp(i,j)表示切割小木棍i-j所需要的最小花费 // 则状态转移为dp(i,j) = min{dp(i,k) + dp(k,j) + a[j]-a[i]) // 其中k>i && k<j // a[j] - a[i] 为第一刀切割的代价 // a[0] = 0,a[n+1] = L; // dp数组初始化的时候dp[i][i+1]的值为 0,这表示 // 每一段都已经是切割了的,不

POJ 1011 - Sticks 题意:    一把等长的木段被随机砍成 n 条小木条    已知他们各自的长度,问原来这些木段可能的最小长度是多少 分析:    1. 该长度必能被总长整除    2. 从大到小枚举,因为小长度更灵活, 可拼接可不拼接    3. 因为每一跟木条都要用到, 故若轮到其中一根原始木段选它的第一根木条时,若第一根木条若不满足,则显然第一根木条在接下来任何一根原始木段都不会满足,故无解    4. 由于所有棒子已排序,在DFS时,若某根棒子未被选,则跳过其后面所有与
