what is nine digit zip code

Question: For multiple groups of data, each group calculates the N number containing '123' (cannot be disconnected), for example, 1: 666, 2: 1666,14: 666. Question: I didn't think about the AC automatic solution, but I didn't know the digital DP. Here there is a digital tree similar to the digital DP, but it is different from the digital DP. Digital tree: Splits the number N into multiple segments like a li

Mysql uses the bigint field to store the 10-digit mobile phone number, which is truncated. How can I store a mobile phone number in the BIGINT field every time. No matter what the 11-digit number is, only 4294967295 and echopow (4294967296) are displayed; //

The Fibonacci sequence (Fibonacci Sequence), also known as the Golden Division sequence. In mathematics, the Fibonacci sequence is defined recursively as follows: F0=0,f1=1,fn=f (n-1) +f (n-2) (n>=2,n∈n*) in modern physics, quasi-crystal structure, chemistry and other fields, the Fibonacci sequence has a direct application, now I from the angle of the algorithm, This is accomplished using both recursive and
