int k; System.out.print("Enter the value of rows: "); int R = kb.nextInt(); System.out.print("Enter the value of cols: "); int C = kb.nextInt(); for(int i = 1; i<=R; i++){ k = ?; //Q1: what to start at each line-i?

and displays a comma-separated grid of numbers where R represents the number of rows and C represents the number of columns. The output will display in column-major order (see in the assignment printGrid.java). The numbers shown increase sequentially down each column and wrap to the top of the next column to the right once the bottom of the current column is reached. Assume both R and C are positive (>0). For instance, if the user enters a 3 for R and 1 for C, your program should display:

1 2 3 If the user enters a 4 for R and 3 for C, your program should display:

1, 5, 9 2, 6, 10 3, 7, 11 4, 8, 12
