给你一个字符串; 里面只包括a和b; 让你把里面的”ab”子串全都去掉; 方式是, 每次操作可以把”ab”替换成为”bba”; 直到整个字符串里面没有”ab”子串为止 【题解】 从ab开始 ab->bba 左边再加一个a的话 即aab 就相当于在bba左边加了一个a abba -> bbaba bbbbaa 会发现就是最左边那个a一直在往...

We have a string of letters 'a' and 'b'. We want to perform some operations on it. On each step we choose one of substrings "ab" in the string and replace it with the string "bba". If we have no "ab" as a substring, our job is done. Print the minimum number of steps we ...

[CF805D] Minimum number of steps(找规律,贪心) 题目链接:http://codeforces.com/contest/805/problem/D 题意:给一个字符串只有a、b,给一个操作ab->bba,现在希望让字符串不包含ab。问多少次操作? 手动模拟下发现倒着来会得到最优解,每次ab->bba 操作会让b多一个,这会影响前面的a。考察最靠右的a,它...

So for example a string like "SOOOXOE" (where "O" represents a free space and "X" represents an obstacle) and there's ansvalue of 3. The minimum number of moves in this case to get from S to E is 2. But in a case like "SOOOXXOE" with the samesvalue, the minimum number of...
Sequences of minimum steps to reach to a smaller number in 3n+1 problem were studied through the number classification. A general formula for this process was given by introducing a novel position of 1 function in a sequence. Thus, the conditions of this process for infinite numbers were give...
