在前部分删除一个字符的代价是22(因为要先按right再按backspace),在后部分删除一个字符的代价是11。因此: fi,j,0←min(fi,j,0,fi−1,j,0+2)fi,j,0←min(fi,j,0,fi−1,j,0+2) fi,j,2←min(fi,j,2,fi−1,j,2+1)fi,j,2←min(fi,j,2,fi−1,j,2+1) 注意这里没有fi,j,1...
In the first sample the editor contains four lines. Let's represent the cursor's possible positions in the line as numbers. Letter s represents the cursor's initial position, letter t represents the last one. Then all possible positions of the cursor in the text editor are described by the...

给定字符串s中的游标位置1<=p<n,游标p表示它在第p和第p+1个字符中间。 游标可以选择以下三种走法: 往左走,p=p-1,前提是左边还有位置。 往右走,p=p+1,前提是右边还有位置。 往相同 元素间隙走,即 假如存在游标q,使得s[p]==s[q],且s[p+1]==s[q+1],那么可以将p诺到q。 现给定m个查询,...
