Now, once you get the logic of printing the previous number pattern you can easily print this pattern. As both are similar except that it contains extra trailing spaces. Hence you only need to add the logic of printing spaces before the number gets printed in the first number pattern. If you point your mouse over the pattern you can actually count total number of spaces per row and can get the logic in which spaces are printed. Now as you can see, each row contains row_number - 1 spaces. Logic to print spaces is-
Lets now write down its code.
First understand the algorithm carefully. Then study the program line-by-line and compare it with the output. Finally, review the explanation section to strengthen your logic and programming understanding.
Rewrite the program without looking at the code. Modify values, conditions or logic and run it again. This helps improve confidence and strengthens coding skills much faster.
