Write two java programs (sequential and parallel) to implement merge sort  that do the following     

 Create a class MergeSortArraySeq that develops a merge sort algorithm to sort an array of integer numbers in sequential.  

 MergeSortArrayThread  that will develop merge sort algorithm to sort an array of integer numbers in parallel. 

 Methods to initialize the array with random numbers from 1-N (e.g., N=10,000, N=100,000).  

  Methods to Sort array in sequential/parallel.  

 Compare the time of both algorithms.  

Draw a diagram to show the relationship between execution time in y-axis and the number of threads in x-axis.  (i.e run your program with different number of threads)
