$\textsf{\large \textbf{Algorithm}}$

   $\text{\textemdash \:\: Getting each letter of the String using \texttt{charAt(int)}.}\\\text{\textemdash \:\: Concatenating letter to itself \texttt{i + 1} times using \texttt{repe\symbol{97}t(int)}.}\\\text{\textemdash \:\: Hence, generating the pattern.}$
