I'm too!!!

          System.out.print(n.mod(new BigInteger("7"); )); }}

you used long arithmetic, it is not best solution, read first post more accurately, it doesn't using any long arythmetic and arrays, collections, etc.

I used the same algoritm! But on Pascal it takes a litle more lines(11 to be exact).

But on Pascal my program works 0.015 seconds, but yours on C - 0.031

My C solution works the same time as yours, but it used 104 КB memory instead of 154 КB in your case.

#include <stdio.h>
int main(void){
    int c,a=0;
    for(;(c=getchar())!='\n';a=(a*10+c-'0')%7);
    printf("%u\n",a);
    return 0;
}

#include <iostream>
int main(void){
    int c,a=0;
    for(;(c=getchar())!='\n';a=(a*10+c-'0')%7);
    printf("%u\n",a);
    return 0;
}
0.015s.

Why does it work? I just don't understand the logic.

Re: AC in 6 line !!! Daniil 1 Dec 2017 17:23

AC in 2 lines:

n = int(input())
print(n%7)

Just 1 line :)

print(int(input())%7)
