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 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.
