I get:
1
2 2
3 3 3
4 4 4 4

Output should be:

1
2 2
3 3 3
4 4 4 4

Codes:

SET SERVEROUTPUT ON SIZE 1000000

DECLARE

i NUMBER;



j NUMBER;


total_lines  NUMBER := 4;  -- Number of lines for the pyramid


leading_ spaces NUMBER;



line_output VARCHAR2(100); -- Variable to hold each line's output

BEGIN

-- Loop through each line to create the pyramid




FOR i IN 1..total_lines LOOP



    -- Calculate leading spaces for centering the line




    leading_spaces := total_lines - i;

    -- Initialize the line output with leading spaces



    line_output := LPAD(' ', leading_spaces);



    -- Append numbers to the line output




    FOR j IN 1..i LOOP



        line_output := line_output || i || ' ';


    END LOOP;




    -- Print the line output



    DBMS_OUTPUT.PUT_LINE(line_output);




END LOOP;

END;

/

the codes do not give the correct output but:

1
2 2
3 3 3
4 4 4 4

PL/SQL procedure successfully completed.

Instead of
1
2 2
3 3 3
4 4 4 4

It should be:

1
2 2
3 3 3
4 4 4 4

Any help,

Thanks,
