Code Implementation

Explanation

The Alphabet D Pattern creates a shape that resembles the letter D using asterisks. The pattern consists of five parts: the top horizontal line, the top curved part, the middle part, the bottom curved part, and the bottom horizontal line. The algorithm ensures that n is odd to create a symmetrical D. The horizontal lines are created by filling a portion of the row with stars. The curved and middle parts are created by placing stars at the first and last positions, with spaces in between to create the hollow effect. The positions of the stars are carefully calculated to create the curved shape of the letter D.
