00001011B取反=11110100B，加1=11110101B，11110101B是-00001011B的补码表示 则00001101B-00001011B=00001101B+11110101B=00000010B 验算：1101B=13D，1011B=11D，13D-11D=2D=00000010B与上边运算结果一致

void swap(node*a,node*b) { 处理a与b相邻的情况， 基本思路：将a指向b的邻边指向自己，将b指向a的邻边指向自己，交换的时候就不会出错 if(a->left=b){ a->left=a;b->parent=b;} else if(a->right=b){ a...

中的a设置进去，当然这里的a经过实例化后成员变量a.b是null,然后再设置a中应用的b，此时B中的a是不完整的，然而最后一句f1.set(b,a);再补充设置b中的a，就完整了。运行结果如下：System.out.println("-");System.out...
