You need to construct a binary tree from a string consisting of parenthesis and integers. The whole input represents a binary tree. It contains an integer followed by zero, one or two pairs of parenthesis. The integer represents the root's value and a pair of parenthesis contains a child bi...
except we can't omit the first parenthesis pair to break the one-to-one mapping relationship between the input and the output. 这道题给我们了一个二叉树,让我们创建对应的字符串,之前有一道正好反过来的题Construct Binary Tree from String。对于二叉树的处理,递归肯定是王道啊。想想如何来实现递归函数,...

接着交换任意两个连续位置的special binary string,取lexicographically最大的。不过这还不算完,注意:At the end of any number of moves,所以还需要迭代一波,直到max不再变化为止,即找到了最大值。很奇怪,为什么max不再变化就说明取到了最大值呢?我只能说,因为上述算法就是单调递增的。。。 Java版本: 代码语言...
