Nanjing Motorola pen exam (written examination in October 21)

I am mainly looking for software developers and the written examination questions are also programming.
There are C language programming and JAVA programming, as well as the basic knowledge of wireless networks, and finally a smart question, the content is roughly as follows:

1. multiple choice questions (including technical questions and logic reasoning questions)
I still remember:
1: Protocol Based on which wireless communication is implemented (802.11)
2: Probably the void pointer allocates some memory and then asks the pointer's sizeof
3: byte storage sequence in the 8086 chip and sun Chip (which is the high end and which is the low segment)
4: How to determine if an integer is an even number?
5: there is a map built with or with a door to ask what the output result is.
6: I ++ and ++ I
7: garbage collection in java
8: logical question: the question provides some conditions for you to answer questions.
9: Some for loops are provided to determine which is an infinite loop.
.
2. Program questions:
1: Converting 3D arrays and one-dimensional arrays
2: print a graphic
3: Find another string in one string (same as the trend)

3. Smart question
The King will kill four people and give them the last chance. If they cannot answer this question, all four will be killed. If one is correct, no four will be killed.
The four men numbered A, B, C, and D. The king took out four hats, two white and two black ones, and put them on. The hats were very small and they could not see their own hats, let them come to the front of a wall and let a stand on one side of the wall. B, C, and D stand on the other side of the wall, and B, C, and D stand in a straight line, B can only look at the wall, but can't see C, D, C. Can See B, can't see ding, ding can see B, c

Now the king asked them to say the color of their hats. As long as the first person answered the correct question, they could not kill them. If the first one answered the wrong question, they would kill them all,
Who will answer the question first? Why?
