Implement a buddy-allocator via c++ using a vector of linked lists. Also redefining these functions

2. Support your own alloc() and free() functions char* alloc (int x); // Gives back the address of a contiguous chunk of memory // that is at least x bytes long if such memory region is // not available, a NULL pointer is returned. void free (char *addr); // Given the address, frees up the memory region starting // at that address (i.e., consider it as free again for // future alloc() calls) 2.
