Wondering whether everything would be simpler if we just got rid of the digit 5? Let's try!\r\n\r\nIn a world without 5's, positive integers may be represented using a base-9 notation that uses only the digits 0, 1, 2, 3, 4, 6, 7, 8, and 9. We'll call this the \"missing-5\" notation. The following list shows the first 100 positive numbers (i.e. 1 through 100) using \"missing-5\" notation:\r\n\r\n '1' '2' '3' '4' '6' '7' '8' '9' '10' '11' \r\n '12' '13' '14' '16' '17' '18' '19' '20' '21' '22' \r\n '23' '24' '26' '27' '28' '29' '30' '31' '32' '33' \r\n '34' '36' '37' '38' '39' '40' '41' '42' '43' '44' \r\n '46' '47' '48' '49' '60' '61' '62' '63' '64' '66' \r\n '67' '68' '69' '70' '71' '72' '73' '74' '76' '77' \r\n '78' '79' '80' '81' '82' '83' '84' '86' '87' '88' \r\n '89' '90' '91' '92' '93' '94' '96' '97' '98' '99' \r\n '100' '101' '102' '103' '104' '106' '107' '108' '109' '110'\r\n '111' '112' '113' '114' '116' '117' '118' '119' '120' '121'\r\n\r\nYou may notice that this is simply the sorted list of positive numbers which do not contain the digit 5 in their decimal representation. \r\n\r\nYour function should convert a positive decimal number N into its \"missing-5\" notation. For example\r\n\r\n dec2missing5(20)\r\n\r\nshould return _'22'_ (the 20th positive number in missing-5 notation), and\r\n\r\n dec2missing5(100)\r\n\r\nshould return _'121'_ (the 100th positive number in missing-5 notation)\r\n\r\nGood luck!\r\n\r\n_Small print_: Your function may output a number, a char array, or a string; whatever you find simpler (e.g. in the example above, valid outputs are 121, '121', or \"121\").
