Given the following heap diagram with block headers, requiring double-word alignment, and using a next-fit placement policy: 0x 00 0x 08 0x 10 0x 18 0x 20 0x 28 0x 30 0x 38 0x 40 16/0 8/0 8/0 If the block at address Ox 24 was the most recent allocated, what address is assigned to ptr for the heap request below: ptr = malloc (2 * size of (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
