This memory dump shows the state of the heap after this allocation. How many free blocks are in the heap? Do not include the prologue/epilogue/padding in your count. [free] How many allocated blocks are in the heap? Do not include the prologue/epilogue/padding in your count. [alloc] If mm_sbrk is called at this point, what address will it return? Enter the value in hex, starting with 0x and with all letters lowercase. [sbrk] What are the first 8 bytes of user payload data in this allocated block? Enter the value in hex, starting with 0x and with all letters lowercase. [first]
