There are different types: T1. Any four cards of the same rank. In this type, the bigger card decides who w

2、ins. For example: 3,3,3,3 6,6,6,6 第2題： 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 第3題： T3. Any three cards of the same ra

3、nk, In this type, the higher three same cards wins. For example: 3,3,3,2 2,2,2,A 第4題： 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 exa

4、mple: 3,3,4,4 4,2,4,2 第5題： 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.

5、t card decides who wins. For example: A,K,Q,9 10,Q,A,K We dont take the suit into consideration.

6、 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

7、 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 第7

8、題： 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 clos
