Given the following heap diagram using block headers with only a-bits, requiring double-word alignment, and using a next-fit placement policy: Ox_00 Ox08 Ox_10 Ox_18 0x 20 Ox_28 Ox 30 Ox 38 Ox_40 16/1 16/0 8/1 8/0 8/1 8/0 1 If the block at address Ox_24 was the most recently allocated, what address is assigned to ptr for the heap request below: ptr = malloc (2 + sizeof(char)); Use the same format for your answer as shown in the diagram above "Ox_NN" without any spaces, no quotes and where N is a digit
