********************
Logic to print above pattern is same as hollow mirrored rhombus star pattern. The only thing we need to change here is, we need to iterate through M rows and N columns (where M is total rows to print and Nis total columns to print).
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.
