| // this implementation use xor to show the capability over pointers. | |
| // let have 4 nodes A, B, C, D with their respective `next` pointer having | |
| // a reference to the next and previous node(which make the list double linked). | |
| // | |
| // the linked list is built backward(new node become head). This implementation state that. | |
| // | |
| // A.pxor = B.xor(null) which is B. | |
| // B.pxor = A.xor(C) which serve us to find both A & C | |
| // C.pxor = B.xor(D) which serve us to find both B & D | |
| // D.pxor = C.xor(null) which point to the prev node. |
