Patterns:
=========
Syntax:
	outerloop_for_row{
		innerloop_for_column{
		}
	}
	

pattern ==> divided into rows
each row can be divide into columns

For the square patterns:
	number of rows and number of columns must be equal

Q_1: WAP TO PRINT THE SQUARE PATTERN WITH ROW NUMBER.
PATTERN:
	row_1:	1	1	1	1
	row_2:	2	2	2	2
	row_3:	3	3	3	3
	row_4:	4	4	4	4

class SquarePattern{
    public static void main(String[] args)
    {
        // outer loop is for getting rows
        for(int row = 1;row <= 5;row++)
        {
            // inner loop for getting the columns
            for(int col = 1;col <= 5;++col)
