Title Link: BZOJ-3129Problem analysisThe idea of using the partition method, if there are no restrictions, then the program number is C (m-1, n-1).If there is a limitation of Xi >= Ai, then we can subtract the M from Ai-1, which is equivalent to a

Recently done a template problem, the difficulty is general, you can learn a quick power, attached to the rules of the modulo operation, /* Modulo arithmetic rules(A + b)% P = (a% p + b% p)% p (1)(A-B)% P = (a% p-b% p)% p (2)(A * b)% P = (a% p * b%
