Given two integer arrays **A1[ ] **and **A2[ ] **of size **N** and **M** respectively. Sort the first array **A1[ ] **such that all the relative positions of the elements in the first array are the same as the elements in the second array **A2[ ]**.

See example for better understanding.

**Note**: If elements are repeated in the second array, consider their first occurance only.

**Example 1:**

**Input:
**N = 11
M = 4
A1[] = {2, 1, 2, 5, 7, 1, 9, 3, 6, 8, 8}
A2[] = {2, 1, 8, 3}
**Output:
**2 2 1 1 8 8 3 5 6 7 9**
Explanation: **Array elements of A1[] are
sorted according to A2[]. So 2 comes first
then 1 comes, then comes 8, then finally 3
comes, now we append remaining elements in
sorted order.

**Example 2:**

**Input:
**N = 11
M = 4
A1[] = {2, 1, 2, 5, 7, 1, 9, 3, 6, 8, 8}
A2[] = {99, 22, 444, 56}
**Output:
**1 1 2 2 3 5 6 7 8 8 9**
Explanation: **No A1[] elements are in A2[]
so we cannot sort A1[] according to A2[].
Hence we sort the elements in non-decreasing
order.

**Your Task:**

You don't need to read input or print anything. Your task is to complete the function **sortA1ByA2()** which takes the array **A1[ ]**, array **A2[ ]** and their respective size **N** and **M** as input parameters and returns the sorted array **A1[ ] **such that the relative positions of the elements in **A1[ ]** are same as the elements in **A2[ ]**. For the elements not present in **A2[ ]** but in **A1[ ]**, it appends them at the last in **increasing **order.

**Expected Time Complexity:** O(N * Log(N)).

**Expected Auxiliary Space:** O(N).

**Constraints:**

1 ≤ N, M ≤ 10^{6}

1 ≤ A1[i], A2[i] ≤ 10^{6}
