1. In JavaScript, the arguments object is a more specific object, which is actually a built-in property of the current function. Arguments is very similar to an array, but is not actually an array instance. Can be confirmed by the following code (of course, in the function Funcarg, the call arguments is not necessarily written funcarg.arguments, write arguments directly).1 ARRAY.PROTOTYPE.TESTARG = "Test";

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,
