Go vs Other Languages

Go CPP
Memory Management Go has Automatic Garbage Collection, which means memory
allocation and deallocation are handled by the runtime		 CPP programmer has to do memory management using new, delete.
Structural Differences No hidden function as compared to c++ 

type ListNode struct {
    Val int
    Next *ListNode
}
CPP have hidden functions, which can add overhead 

class ListNode {
    int val;
    ListNode *next;
public:
    //constructor
    //destructor
};
