The logic to print the above pattern is almost similar to the pattern we just printed. In this pattern we only need to add logic of printing spaces just before number gets printed. There are N - i spaces per row (where i is the current row number). If you want to see or count spaces, you can hover on to the pattern.
Step-by-step descriptive logic:
First read the algorithm, then study the program code line by line. After that, compare the code with the output and finally go through the explanation. This approach helps learners understand both the logic and the implementation properly.
After understanding this example, try to rewrite the same program without looking at the code. Then change some values or logic and run it again. This helps improve confidence and keeps learners engaged on the page for longer.
