It's a simple question, but there's a bunch of disgusting boundaries.After gouging out the disgusting border:Suppose we know that the cyclic section on both sides is B1,B2Where H is the first time to reach the target is A1,A2And know that for the answer TT=a1+b1*t1=a2+b2*t2You can enumerate T1 to see if there is a viable solution.And because the LCM (B1,B2) began to circulate.and B1*b2So we enumerate the range of T1 in [0,mod]If there is no solution within this range, there must be no solution#i

The highest level is the CSS style defined by id -->

Original formula AX + by = c => Ax1 + by1 = gcd (A, B ); If A, B, and C are any integers and D = gcd (a, B), a group of solutions for ax1 + by1 = D is (x1, Y1 ), when C is a multiple of gcd (a, B), one of them is (x1 * C/D, Y1 * C/D); C is not gcd (A, B) no solution A frog appointment is an example. According to the question, it is easy to name the equation: (x + MS)-(Y + NS) = K * l; (k = 1... n) deformation to the Extended Euclidean FormulaYo
