You are given two sorted arrays that contain only integers. Your task is to find a way to merge them into a single one, sorted in **ascending order**. Complete the function `mergeArrays(arr1, arr2)`, where `arr1` and `arr2` are the original sorted arrays.
You don't need to worry about validation, since `arr1` and `arr2` must be arrays with 0 or more Integers. If both `arr1` and `arr2` are empty, then just return an empty array.
**Note:** `arr1` and `arr2` may be sorted in different orders. Also `arr1` and `arr2` may have same integers. Remove duplicated in the returned result.
## Examples
Happy coding!
def merge_arrays(arr1, arr2):
    arr1 = arr1+arr2
    res = []
    for i in arr1: 
        if i not in res: 
            res.append(i)
    return sorted(res)
def merge_arrays(arr1, arr2):
    arr1 = arr1+arr2
    res = []
    for i in arr1: 
        if i not in res: 
            res.append(i)
    return sorted(res)
