Copy the program Flatten.java and implement the TBI (To BeImplemented) methods flatten(int[][]) andflatten(String[][]).
You will need to study the code in theprint(int[]) andprint(String[][]) methods to figure out how theflatten() methods “flatten” their 2-dimensional arrayparameter into their 1-dimensional array return value.
Your program cannot contain any importstatements.
The output of your program must match the following. {outputfile}
The output:
{ }
{ 1, }
{ 1, 2, }
{ 1, 2, 3, }
{ 1, 2, 3, 4, }
{ 1, 2, 3, 4, 5, }
{ 1, 2, 3, 4, 5, 6, }

{ “while”, “do while”, “for”, }
