Operating systems and any code that allows programs to communicate with each other rely upon understanding how data is represented in memory, and the purpose of this question is to practice that. Assume that pointers are 64 bits in length, and the following data structure, variables, and code that would operate on the data: Draw the block of memory containing the els array with separate boxes for each structure member. In each box for integers (the uint32_t variables), write in the value that is in that block. For the pointers, if it would have the value 0 , write 0 . Otherwise, draw an arrow from the pointer cell to the beginning of the element it is pointing at. As an example, if the code were: Assignment_grades gr[1] ={3,1,5,9, NULL }; gr[0] next =gr; the drawing could be
