The above pattern is similar to the pattern we just printed except the trailing spaces. The logic of this pattern would be similar as previous pattern we did, we only need to add logic to print trailing spaces before printing numbers. There are i - 1 spaces per row (where i is the current row number). To see or count total spaces per row you can hover mouse pointer to the pattern above.
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.
