题意:给一个整数序列,输出每次反转的位置,输出0代表排序完成.给一个序列1 2 3 4 5,这5就是栈底,1是顶,底到顶的位置是从1~5,每次反转是指从左数第i个位置,将其及其左边所有的数字都反转,假如反转位置2,则1 2 3 4 5就变成 4 3 2 1 5. 问怎样经过最少次数的反转能得到升序12345. 思路:每次产生一个最大的数字到右边,经过n次就升序了.每次产生可能需要两次反转,也可能1次就搞定,可能0次.0次是因为该数已经在最终位置上:1次搞定是因为最大数已经在栈顶(最左边),一反转…

                                                 Stacks of Flapjacks  题目链接:Click Here~ 题目描写叙述:     给你n个数.要你得到的最后结果是从下到大排序.可是给出的序列不一定是有序你.要通过你的调整.问:要经过哪几个位置上的数的调整? 算法分析:     一開始,我的思路是直接模拟一边消除逆序数就能够了,由于我看数据非常小,仅仅有30.可是提交之后却TEL了. 后来上网查了一下.看到有一个人的思路还是非…

[UVa120] Stacks of Flapjacks 算法入门经典第8章8-1 (P236) 题目大意:有一个序列,可以翻转[1,k],构造一种方案使得序列升序排列. 试题分析:从插入排序即可找到思路.每次我们优先地将没有到自己位置上的.最大的数挪到自己的位置上. 为什么可以这样做呢?难道不会改变已经排好序的么. 不会,因为我们从大往小处理,翻转的是前面的一段,而排好序的是后面一段,因此肯定不会打乱后面的. 对于每一个数,设其下标为pos,已经排好序的有x个,那么我们先将pos其变为1,即翻…

3.3 Imagine a (literal) stack of plates. If the stack gets too high, it might topple. Therefore, in real life, we would likely start a new stack when the previous stack exceeds some threshold. Implement a data structure SetOf Stacks that mimics this.…
