back to boardA question regarding the question..... Posted by Jaideva 10 Nov 2013 01:06 The value of N is <= 50, so we are talking about a 100 digit number atmost.....how then the upper limit of S is 1000.....shouldn't it be 900.....or are we supposed to return 0 when (2*N*9) < S. Am I missing something ????? Edited by author 10.11.2013 01:07 Nevermind.....I solved it..... Few useful insights :- (i) if S > (2*9*N) output 0; (ii) if S = 0 output 1; (otherwise you would get WA for test 5). Edited by author 10.11.2013 02:27 |
