发帖数: 2413 | 1 AVL is much better than REE because of its heavy RE if AVL's announcement
is real. However, it is hard for AVL to mine HRE due to poor facility (no
good public electricity, water, and traffic over there) around AVL's
resources. The cost will be huge if they decide to mine.
Now It is safe to keep the AVL stock but not options. I will wait for news
from China. If China keeps her words to cut the quota, AVL will reach $10
soon. |

The Long Case for Avalon Rare Metals

Rare Earth Elements or REEs seem to be the newest big mover on Wall Street.
Although most have heard of them, they do not know what their use is. The
best way to identify them is by going back to chemistry class and looking at
a periodic table. Here is an easier introduction.

I just want to remind the people who buys AVL calls. AVL's new offering
may come soon! Buying AVL stock position is till fine and AVL will be
$15~25 in six months. However, you should be careful of new share offering
for short term. |

发帖数: 2413 | 11 Watching and waiting is not bad! MCP and REE doesn't increase much. If you
buy the dip, you may have some earning; If you play with options, you even
have certain loss.
However, I made a mistake with AVL. I knew AVL would be up a lot because
of its HREE, but I didn't know it is so strong.
Today I bought some AVL near market closing.

发帖数: 2413 | 17 AVL will get double ($15~18) by the end of this year!
I feel that AVL are much better than REE and MCP though AVL has no
production so far.
Check this by the end of this year!
Last year, when MCP was $27, I said it will be $60 this year. |

发帖数: 2413 | 18 If market is down for several months, AVL will be $4~5? REE will be $4~5?
MCP will be $20~30? though I predicted AVL would go higher.
If market is good, all of MCP ree avl would surge up again? |

发帖数: 7404 | 45 这个递归解法简洁但低效。应该用DP，在hash table里把每个节点和子树深度记下来？
int getHeight(Node* root)
{
if (root === NULL) return 0;
return max(getHeight(root->left), getHeight(root->right)) + 1;
}
bool isAVL(Node* root)
{
if (root == NULL) return true;
return abs(getHeight(root->left) - getHeight(root->right)) <= 1
&& isAVL(root->left) && is AVL(root->right);

AVL is easier but may backtrack, so rotation cost is not
guaranteed O(1). Total cost is still O(n) but the constant factor is worse. |

发帖数: 207 | 47 如果出现类似“你了解红黑树/AVL树吗？请实现一个”，我认为或者这个面试官是脑残
，或者是诚心想让你挂，不用理他，直接推门离开就好，然后写信告诉HR情况。当然，
这家肯定就挂了，但是遇上脑残，你呆下去还是挂，所以省省时间吧。毕竟公司那么多
。花时间准备红黑树纯属浪费时间，不如多做leetcode。
除了在这，从没听说过有让写红黑树之类的，如果有人问我，我会直接说“go fuck
