本文是一份亚马逊2015校招在线测评笔试题,全e文,感兴趣的同学参考下。

A standard 52-card deck, which contains 2, 3, …, J, Q, K, A. Pick four cards from the deck as a hand. Provide a function to figure out who is the winner of given two hands.

There are different types:

T1. Any four cards of the same rank. In this type, the bigger card decides who wins.

For example: 3,3,3,3< 6,6,6,6

T2. Any string with all four cards, and in such case (consecutive), ‘A’ can count as either a high or a low card. Otherwise, A is a highest card. In this type, the highest card decides who wins.

For example: A,2,3,4< J,Q,K,A

T3. Any three cards of the same rank, In this type, the higher three same cards wins.

For example: 3,3,3,2> 2,2,2,A

T4. Any two cards of the same rank together with another two cards of the same rank. In this type, if two hands share same higher Pair, the bigger another Pair decides who wins. Otherwise, bigger Pair wins.

For example: 3,3,4,4> 4,2,4,2

T5. Any two cards of the same rank. In this type, bigger Pair wins. If two hands share same Pair, the bigger Third decides who wins. Otherwise, the bigger Fourth wins.

For example: 3,3,7,4< 3,3,7,5

T6. Any hand not in the above-mentioned hands. In this type, the highest card decides who wins.

For example: A,K,Q,9< 10,Q,A,K

We don’t take the suit into consideration. If two hands in different type, the rule is: T1>T2>T3>T4>T5>T6

You will get two lines as input:

6,3,4,5

3,4,5,6

You should output the result:

0

If the first two line is bigger than the second line, the result should be 1. If the first line is smaller than the second line, the result should be -1. If they are equal, you should return 0.

If a participator cheats in this game, the number of the same card will be more than four in the two hands. In this case, you should return -2.

Symmetric number is a kind of non-negative number which looks the same as its inversion. For example, ”12321”is a symmetric number. Given any number n represented by a string, find the next symmetric number which is bigger than n.

Here are two examples,

Sample 1:

Input:

123

Output:

131

Sample 2:

Input:

12321

Output:

12421

YOUR ANSWER:

———————–

Common Ancestor(Programming)

Question:

A endless Complete Trinary Tree. Node ID is its back-and-forth order in level travel. Find the closest common ancestor.

(“Complete Trinary” means each node has three children, neither more or less)

Example:

The node 13 and 15 have a closest common parent12

The node 16 and 10 have a closest common parent 1

If one Node is the ancestor of the another one, that Node is the closest common ancestor.

Input:

You will get two Nodes’ ID like:

13  9

Output:

You should return the closest common parent node ID like:

0
