OK,因为是连续两个special binary string位置的交换,所以我们可以遍历S的每个位置,求出每个位置可能的special binary string,用map记录。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...

以3*3为例,从第二行第二列开始,到当前位置的方式有a[1] = a[1] + a[1-1] 种。本质上,ways[j] += ways[j - 1]中,waya[i-1]表示的是从左边过来的路径,waya[i]表示从上边过来的路径,符合dp[i][j] = dp[i - 1][j] + dp[i][j - 1]内涵,只是不断进行刷新。
