o题解！！！

#include <iostream>
using namespace std;
int oc[10] = {1, 0, 0, 0, 1, 0, 1, 0, 2, 1};
int main() {
int m = 0;
int r = 0;
for (int num = 1; num <= 99; num++) {
int c = 0;
int ts = num / 10;
int us = num % 10;
c += oc[ts];
c += oc[us];
if (c > m) {
m = c;
r = num;
}
}

cout << r << endl; 

return 0;

}
