[퀴즈_46] 카프리카 넘버 구하기

제시된 숫자 몇 개는 아닌 것 같은데요... 아마 중간에 있는 0을 무시한 결과인듯... 
1, 9, 45, 55, 99, 297, 703, 999, 2223, 2728, 4950, 5050, 7272, 7777, 9999, 17344, 22222, 77778, 82656, 95121, 99999, 142857, 148149, 181819, 187110, 208495, 318682, 329967, 351352, 356643, 390313, 461539, 466830, 499500, 500500, 533170, 538461, 609687, 643357, 648648, 670033, 681318, 791505, 812890, 818181, 851851, 857143, 961038, 994708, 999999

수식은 만 이하로,,,
