Poj 2028 when can we meet? (Another question)

[Description]: N indicates several members. Q indicates that the meeting is valid only when there are several members. In the next n rows, the first number in each row indicates that the row has m numbers, which days does the member have. Finally, let's find the meeting day as soon as possible.

[Analysis]: for simple questions, see the code.

// 248 K 47 Ms # include <iostream> using namespace STD; int M [101]; int N, Q; int main () {int m; int M1; while (1) {CIN> N> q; If (n = 0 & Q = 0) break; memset (M, 0, sizeof (m )); while (n --) {CIN> m; For (INT I = 0; I <m; I ++) {CIN> m1; M [M1] ++ ;}} int max = 0; int A; For (Int J = 0; j <= 100; j ++) {If (M [J]> MAX) {max = m [J]; A = J ;}} if (max >= q) cout <A <Endl; elsecout <"0" <Endl;} return 0 ;}
