********************
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 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.
