5. A method named duplicateRow that takes a 1-dimensional array of double values and an integer. It returns a 2-dimensional array that is formed by duplicating the passed 1- dimensional array as rows as many times as defined in the passed integer. For example, if the array {1.1, 2.2, 3.3, 4.4, 5.5} and the integer 3 are passed to this method, it must return the 2-dimensional array: 1.1 2.2 3.3 4.4 5.5 1.1 2.2 3.3 4.4 5.5 1.1 2.2 3.3 4.45.5

5. A method named duplicateRow that takes a 1-dimensional array of double values and an
integer. It returns a 2-dimensional array that is formed by duplicating the passed 1-
dimensional array as rows as many times as defined in the passed integer.
For example, if the array {1.1, 2.2, 3.3, 4.4, 5.5} and the integer 3 are passed to this
method, it must return the 2-dimensional array:
1.1 2.2 3.3 4.4 5.5
1.1 2.2 3.3 4.4 5.5
1.1 2.2 3.3 4.4 5.5
6. A method named concatenate that takes two 2-dimensional arrays of double values and
returns a new 2-dimensional array that results from concatenating the two arrays by
combining their rows.
For example, if the first
1.1 3.3 5.5 7.7
array
is:
1.1 2.2
7.7 8.8 2.2
and the second array:
9.9 7.7 4.4
8.8 6.6
It must return the following array:
1.1 3.3 5.57.7
1.1 2.2
7.7 8.8 2.2
9.9 7.7 4.4
8.8 6.6

7. A method named addRow that takes two parameters: the first is a two-dimensional array
of doubles, and the second is a one-dimensional array of doubles. The method must
return a new two-dimensional array of doubles that results from adding the second
parameter (one-dimensional array) as a last row to the first parameter (two-dimensional
array).
The following implementation forms the new array by making it point to the same rows
of the 2-dimensional array and the 1-dimensional array:
public static double[][] addRow(double [][]array, double[]row){
double[][] newArray = new double[array.length+1][]);
for(int i=0; i<array.length; i++)
newArray[i]=arrsay[i];
newArray[newArray.length-1]=row;
return newArray;
}
In this assignment, you must implement this method in another way. Your
implementation must not work by copying references. Instead, it must create new array
for each row and copy the individual elements.
