    val charArray2D = arrayOf(
        arrayOf('K', 'o', 't', 'l', 'i', 'n'),
        arrayOf('p', 'r', 'o', 'g', 'r', 'a', 'm', 'm', 'i', 'n', 'g'),
        arrayOf('l', 'a', 'n', 'g', 'u', 'a', 'g', 'e')
    )

    // Row 1 (second row)
    val rowIndex = 1
    val selectedRow = charArray2D[rowIndex]

    // Convert the row to a string
    val s = selectedRow.joinToString("")
