There are two main types of compressors: positive displacement compressors and dynamic compressors.
Positive displacement compressors include reciprocating, rotary screw, and rotary vane compressors.
Dynamic compressors include centrifugal and axial compressors.
Positive displacement compressors deliver a fixed volume of air per rotation, while dynamic compressors deliver a variable volume of air.
Positive displacement com...

There are two main types of boilers: fire tube boilers and water tube boilers.
Fire tube boilers have hot gases passing through tubes that are surrounded by water.
Water tube boilers have water flowing inside the tubes while hot gases surround them.
Other types include electric boilers, biomass boilers, and steam boilers.
Boilers can also be classified based on fuel type such as gas, oil, coal, or wood.
Boilers can be furth...

You are provided with the head of a linked list containing integers. Your task is to determine if the linked list is circular.
Detect if a given linked list is circular by checking if it forms a closed loop.
Traverse the linked list using two pointers, one moving at double the speed of the other.
If the two pointers meet at any point, the linked list is circular.
If the faster pointer reaches the end of the list (NULL), the linked list is not circular.
