Time Limit：1s Memory Limit：64MByte

Submissions：990Solved：240

DESCRIPTION

Two octal number integers a, b are given, and you need calculate the result a - b in octal notation.
If the result is negative, you should use the negative sign instead of complement notation.

INPUT

The first line is an integer T(1 <= T <= 1000), indicating the number of test cases.For each case, the first and only line contains two octal integers a, b.(0 <= a, b < 2^32)

OUTPUT

Print the result, one per line, in octal notation.

SAMPLE INPUT

176 7

SAMPLE OUTPUT

67

SOLUTION

输入数据会有点大，所以单纯用%o来输入的话，就会WA，所以代码如下：

#include<stdio.h>#include<math.h>#include<string.h>#include<algorithm>using namespace std;int main(){    int T;    scanf("%d",&T);    while(T--)    {        long  a,b;        scanf("%llo%llo",&a,&b);        if(a>b)        printf("%llo\n",a-b);        else printf("-%llo\n",b-a);    }    return 0;}
