全局变量int n在执行这个函数之后，值改变了，是怎么回事　？我没该n的值啊　！
void segment::construct (int left, int right)
{
     if (left < right)
     {
              l = left;
              r = right;
              col = nocolor;
              if (left + 1 < right)
              {
                       lchild = &tree[Len ++];
                       rchild = &tree[Len ++];
                       int mid = (left + right) / 2;
                       lchild->construct (left, mid);
                       rchild->construct (mid, right);
              }
              else
              {
                  lchild = rchild = NULL;
              }
     }
}

• 数组越界了吧，覆盖了n (0) YUMEN19850720 2007-03-15 18:29:09
