Before we get into this pattern I recommend you to look to the given pattern carefully for a minute. The pattern contains N rows (where N is the total rows to be printed). Each row contains exactly N - i + 1columns (where i is the current row number).
Step-by-step descriptive logic:

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

Master Programming Through Practical Examples

Improve your coding logic, problem-solving skills and programming confidence by practicing real-world examples with explanations.

🎯 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.
