Question

we have proven that the computational time complexity of 
mergesort is O(n * log2n). Perhaps the time complexity of mergesort can be improved further by 
separating the array into three parts instead of two.


Start by implementing a method called merge3. This method should take three sorted arrays as 
inputs and return a sorted array consisting of all elements of the three input arrays.

 

public static int[] merge3(int[] a, int[] b, int[] c) {
        return new int[] {-1};
    }
 
* must be done in this format and in java
