#D4416. Merge Sort
Merge Sort
Merge Sort
Write a program of a Merge Sort algorithm implemented by the following pseudocode. You should also report the number of comparisons in the Merge function.
Merge(A, left, mid, right) n1 = mid - left; n2 = right - mid; create array L[0...n1], R[0...n2] for i = 0 to n1-1 do L[i] = A[left + i] for i = 0 to n2-1 do R[i] = A[mid + i] L[n1] = SENTINEL R[n2] = SENTINEL i = 0; j = 0; for k = left to right-1 if L[i] <= R[j] then A[k] = L[i] i = i + 1 else A[k] = R[j] j = j + 1
Merge-Sort(A, left, right){ if left+1 < right then mid = (left + right)/2; call Merge-Sort(A, left, mid) call Merge-Sort(A, mid, right) call Merge(A, left, mid, right)
Notes
Constraints
- n ≤ 500000
- 0 ≤ an element in S ≤ 109
Input
In the first line n is given. In the second line, n integers are given.
Output
In the first line, print the sequence S. Two consequtive elements should be separated by a space character.
In the second line, print the number of comparisons.
Example
Input
10 8 5 9 2 6 3 7 1 10 4
Output
1 2 3 4 5 6 7 8 9 10 34
