Content 给出一个长度为 \(n\) 字符串 \(s\),请将开头为 \(\texttt{ogo}\),后面带若干个 \(\texttt{go}\) 的子串替换成 \(\texttt{***}\),然后输出. 数据范围:\(1\leqslant n\leqslant 100\). Solution 我们考虑遍历每个字符,如果这个字符是 \(\texttt{o}\),并且后面两个字符是 \(\texttt{go}\),那么直接替换成 \(\texttt{***}\),并且往后搜有没有 \(\…

Cracking the Coding Interview(Stacks and Queues) 1.Describe how you could use a single array to implement three stacks. 我的思路:一般堆栈的实现会利用一个数组,这里一个数组若实现3个堆栈,直接考虑把数组划分为3个部分,相当于3个独立的数组,所以就有以下的实现. 但是,这种实现方式的缺点在于均分了每个stack需要的space,但是事先无法确定每个stack是否需要更多的spac…
