Logic to print the given number pattern 1

If you are following my previous posts then you might notice that these two patterns are similar to one of the previous number pattern that I have discussed earlier. Hence, it is recommended to go through it as it will help you to build logic for the pattern we are going to print.

Now considering the first pattern that we need to print.

If you notice, in above pattern if we start from 1^st to 5^th row, the current row number gets printed in every columns. Also number of columns per row is dependent on the current row number (i.e. there are 1 columns in row1, 2 in row2, 3 in row3 and so on). So lets, write down step by step logic to the above pattern.

To iterate through rows, initialize an outer loop from 1 to N (where N is the total rows to be printed).
To print columns per row, initialize an inner loop from 1 to current_row_number (since columns are row dependent). Inside this loop print the value of current_row_number.

And you are done. Lets write down its code.

🎯 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.
