Codes Explanation

• This program shows the prompts to user for enter the number of rows for the half diamond.
• After that it divides the half diamond into two parts: the upper half and the lower half.
• For each part, it iterates through each row using a for loop. Within each row, it prints stars using another nested for loop.
• The number of stars in each row follows a pattern: increasing from 1 to the middle row, then decreasing back to 1.
