Web19 Mar 2024 · As with ordinary generating functions, we determine a generating function for each of the digits and multiply them. For 1s and 2s, since we may have any number of each of them, we introduce a factor of ex for each. For an even number of 0s, we need 1 + x2 2! + x4 4! + x6 6! + ⋅ ⋅ ⋅ = ∞ ∑ n = 0 x2n (2n)!. Web7 Jul 2024 · There is an extremely powerful tool in discrete mathematics used to manipulate sequences called the generating function.
