Total elements is m + n = 11. To get the median of the merged array, how many elements do we need to process in the worst case using the straightforward merge?

1. (a)Just 1 — we can read the median directly from one of the arrays.
2. (b)About 6 — we need to walk up to the median position to know which element it is.
3. (c)All 11 — we must fully merge before we know the median.
