3) Why do AsAm PIs have the lowest success rate in NSF proposals funding
rate, although they may have the higher perhaps even the highest average
publication rate?
NSF just released the following report (See middle of p. 2): The
success rate for proposals from PIs was White 24%; from Hispanics or Latin
PIs was 20%; from Black/African-Am. PIs was 18%; from Asian PIs was 17%. We

发帖数: 23 | 9 小弟在看careercup，其中有一题是求二叉树两个节点的Lowest Common Ancestor。
书中先给出一种解法：

2 if (covers(root.left, p) && covers(root.left, q))
3 return commonAncestor(root.left, p, q);
4 if (covers(root.right, p) && covers(root.right, q))
5 return commonAncestor(root.right, p, q);
6 return root;

8 private boolean covers(Tree root, Tree p) { /* is p a child of root?

发帖数: 1133 | 10 粗看了一下，上面的解法应该不是O(n)的
O(n)解法可以这样，DFS的时候得到p和q的从root到它们的path，这个是O(n)的
然后把其中一个path放进hash set里，另外一个path找到第一个set里存在的node就是
lowest common ancestor，这一步是O(log n)
所以是O(n)的 |

直接问他澄清就是了。
（1）是不是一个node不能是本身的ancestor？ 比如如果p是q的parent, 则lowest
common ancestor是p的parent (而不是p)? |

我用的是top-down策略，即从root向下扫描，如果两个目标点都在左侧或者右侧，则
root移到左节点或者右节点，继续扫描，直到两个目标节点不在同一侧。
小弟不才，在Lintcode上面提交代码始终无法通过，总是在第八个test时fail。实在想
