### Question 2 Rearrange the following code to let the user enter a row number and display the rows of numbers as the example shown below. Assume all the variables have already been declared. **Example Output:** ``` Input number of rows: 4 1 12 123 1234 ``` #### Code Here is the initial code snippet provided: ```java Scanner in = new Scanner(System.in); n = in.nextInt(); System.out.println(""); System.out.print("Input number of rows : "); for (j = 1; j <= i; j++) System.out.print(j); for (i = 1; i <= n; i++) { } ``` #### Instructions Put the line numbers in order in the following blank spaces: ```java ___ ___ ___ ___ ___ ___ ___ ``` ### Explanation of the Code - The program should first prompt the user to enter the total number of rows. - It then constructs each row iteratively, printing the numbers from 1 up to the current row number. Here's the step-by-step breakdown of the correct sequence: 1. Prompt the user to enter the number of rows. 2. Read the user's input. 3. Loop through each row from 1 to the input number. 4. For each row, print the sequence of numbers from 1 to the current row number. 5. Print each row on a new line. ### Correct Line Order Here is the rearranged code in proper sequence: ```java System.out.print("Input number of rows : "); n = in.nextInt(); for (i = 1; i <= n; i++) { for (j = 1; j <= i; j++) { System.out.print(j); } System.out.println(""); } ``` Therefore, the order of the lines is: - Line 1: `System.out.print("Input number of rows : ");` - Line 2: `n = in.nextInt();` - Line 3: `for (i = 1; i <= n; i++) {` - Line 4: `for (j = 1; j <= i; j++) {` - Line 5: `System.out.print(j);` - Line 6: `}` - Line 7: `System.out.println("");` By rearranging the lines in this manner, the program will produce the desired
