integer solution of Pa+qb=c, it is only possible to multiply each solution of P * A+q * b = GCD (P, Q) by C/GCD (p, q).After finding a set of solutions for P * A+q * b = GCD (A, B) p0,q0, you should be given a set of solutions for P * A+q * b = c P1 = p0* (C/GCD (A, b)), Q1 = q0* (C/GCD (b)),P * A+q * b = Other integer solutions of C are satisfied:p = p1 + B/GCD (A, b) * t q = Q1-A/GCD (A, b) * t (where T is an arbitrary integer) p, Q is the solution of all integers of p * a+q * b = c.

DescriptionThe Euler circuit refers to a loop that does not leave the pen on paper, but only once per side of the picture and can return to the starting point. Now given a diagram, ask if there is a Euler circuit?InputThe test input contains several test cases. The 1th line of each test case gives two positive integers, namely the number of nodes N (1 Beam.OutputThe output of each test case is one row, or output 1 if the Euler loop is present, otherwise output 0.Sample Input3 31 21 32 33 21 22 3
