Any two numbers in A[i],a[j] (iWhile merging the sorted two permutations of the processThe elements of the ordered sequence on the right are inserted sequentially into the preceding sequential sequence.E.G. (3 7 12) (5 6 8)Insert 5 in (3 7 12)Because the back is ordered, it assumes that all elements of 5 and left are in reverse order, so there are mid+1.And the left sequence has start1 number than 5, so the reverse number is Mid+1-start1This
