Two Bases CodeForces - 602A （BigInteger c++long long也可以）

哇咔咔 卡函数的

标记一下 c++和java的进制转换函数都是1-36进制的

c++ long long暴力就过了。。。

自己写一个就好了

import java.math.BigInteger;
import java.util.*;
import java.util.Arrays.*;
public class Main {
    static final int maxn = 1002;
    public static void main(String[] args) {

        int n = cin.nextInt();
        int m = cin.nextInt();
        BigInteger a = BigInteger.ONE;
        for(int i=n-1; i>=0; i--)
        {
            str1 = cin.next();
            a = a.add(change(str1, m, i));
        }

        }

        else if(a.compareTo(b) < 0)

    }

        return c;
    }
    
}
