...First, the numbers. Assume the first list is of length a+c and the second one is of length b+c, where c is the length of their common "tail" (after the mergepoint). Let's denote them as follows:
x = a+c
y = b+c
Since we don't know the length, we will calculate x and y without additional iterati...
