设fSfS为把a[]中SS表示的位置上的那些元素变换到A[]中前|S||S|个位置的最小花费。这样我们仅仅知道SS包含哪些位置,而完全不知道这些a[]中的每个元素变换到了A[]中的具体哪个位置。现在我们要将i∉Si∉S加入,那么SS正是所有 “在A[]中的标号比a[i]在A[]中的标号小的元素” 在a[]中的位置。 con...
[ABC232F] Simple Operations on Sequence 题解 我们把问题陈述中的第一个操作称为 "增/减",第二个操作称为 "交换"。在这里,让我们对问题陈述稍加限制,一旦执行了增/减操作,就不能再执行交换操作。换句话说,唯一允许的操作过程是:首先执行任意次数(可能为零)的交换; 然后执行任意次数(可能为零)的递增/递减...
