GCD2 - GCD2
Frank explained its friend Felman the algorithm of Euclides to calculate the GCD of two numbers. Then Felman implements it algorithm
int gcd(int a, int b) { if (b==0) return a; else return gcd(b,a%b); }and it proposes to Frank that makes it but with a little integer and another integer that has up to 250 digits.
Your task is to help Frank programming an efficient code for the challenge of Felman.
Input
The first line of the input file contains a number representing the number of lines to follow. Each line consists of two number A and B (0 <= A <= 40000 and A <= B < 10^250).
Output
Print for each pair (A,B) in the input one integer representing the GCD of A and B.
Example
Input: 2 2 6 10 11 Output: 2 1
Source limit is 1,000 Bytes.

Here, interpreted languages do better than compiled ones. Euclid's algo works in these languages. |

fractions.gcd() got TLE but euclid works fine and got AC with 0.10s in python... |
