📘 Explanation

Logic to print the given number pattern

The above pattern consists of N rows (where N is the total rows to be printed). To since the pattern is in descending order hence, to make things easier we will iterate through rows from N-1 instead of 1-N so now the first row is row5, second row is row4 and last row is row1. Each row contains exactly i columns (where i is the current row number).
The step-by-step descriptive logic of the pattern is:

To iterate through rows, run an outer loop from N to 1 in decreasing order.
To print the columns, run an inner loop from i to 1 in decreasing order. Inside this loop print the value of j (where j is the current column number).

🎯 How to learn from this example

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.

🔥 Practice suggestion

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.
