In the textbook, we found that the number of element visits for merge sort totaled
N + 5nlog₂n. Let's consider sorting 1024 elements. How many visits are needed?

Plugging in the values for N=1024, S1U1B1=16 (assuming a typical cache size), and n=1 (as we are performing the sorting for the entire array at once), we get:
1024 + 5(1)(10)(16)(1 + log2(1024/16)) = 1024 + 5(160)(6) = 105,024
Therefore, the number of visits needed is 52,224 (rounded to the nearest integer), which is option D.
