Question: programming, input two integers n and m, from the series 1, 2, 3 ,...... N is random, so that the sum is equal to M. All possible combinations are required. Analysis: the idea of sub-governance. You can split the problem (m, n) into (m-N, N-1) and (m, n-1 ). Note:

Fermat theorem (Fermat theory) is an important theorem in number theory: if P is prime, and gcd (a,p) = 1, then a(p-1) ≡1 (mod p). That is: If A is an integer, p is a prime number, and A,p coprime (that is, there is only one convention of 1), then the remainder of a (p-1) di

Using the knowledge of permutation and combination, we can calculate that n bit can represent 2 ^ n cases, for example, 3 bit can represent 8 conditions:000 001 010 011 100 101 110 111Now we stipulate that in the n bits, if this bit is 1, then from right to left, how many BITs is this bit: Suppose it is t, then t is selected: for example: in 110,
