📘 Explanation

Logic to print the given number pattern

Once you got the logic of previous number pattern that we just printed, you can easily get the logic of this pattern. As it is almost similar to the first number pattern expect that it contains trailing spaces. Hence we only need to add the logic of printing trailing spaces to the first number pattern program.
To get the logic of this pattern just hover your mouse on the above pattern to see or count total spaces per row. There are total i - 1 spaces per row (where i is the current row number).
The step-by-step descriptive logic to print space:

To print space, run an inner loop from 1 to i - 1. Inside this loop print single blank space.

Only this much you need to do. Lets implement this on code.

🎯 How to learn from this example

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.

🔥 Practice suggestion

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.
