蓝桥杯-历届试题 翻硬币

问题描述

小明正在玩一个“翻硬币”的游戏。

桌上放着排成一排的若干硬币。我们用 * 表示正面,用 o 表示反面(是小写字母,不是零)。

比如,可能情形是:**oo***oooo

如果同时翻转左边的两个硬币,则变为:oooo***oooo

现在小明的问题是:如果已知了初始状态和要达到的目标状态,每次只能同时翻转相邻的两个硬币,那么对特定的局面,最少要翻动多少次呢?

我们约定:把翻动相邻的两个硬币叫做一步操作,那么要求:

输入格式

两行等长的字符串,分别表示初始状态和要达到的目标状态。每行的长度<1000

输出格式

一个整数,表示最小操作步数。

样例输入1

**********

o****o****

样例输出1

5

样例输入2

*o**o***o***

*o***o**o***

样例输出2

1
