回複：thanks a lot. further questions

what do you mean by puzzles?
They are also called brain-teasers/brain-bashers. For example:

There is a closed room with a light in it. Outside, there are 3 light switches. You can flick any of the switches any number of times. You can only open the door and go into the room once. You know that the light is initially off. How can you determine which light switch operates the light?

what kind of coding questions?
For example:

Write a C function to add a element to linked-list.
Write a Java function to count all words in a string using hastable.
