  2. Initialize a boolean in_block_comment to False to track whether we are inside a block comment.
  3. Initialize an empty string buffer to temporarily store characters from the current line that are not part of a comment.
  4. Iterate over each line in the source array. a. If not in a block comment, reset buffer to an empty string. b. Iterate over each character in the line. i. If in a block comment, look for the end of the block comment (*/). ii. If not in a comment, look for the start of any comment (// or /*). iii. If no comment is found, append the character to buffer. c. If the end of the line is reached and not in a block comment, append buffer to result if buffer is not empty.
