A table can contain at most one matching record, which is read from the beginning of the query. Since there is only one record, the field values recorded by this row in the remaining optimization programs can be treated as a constant value. The const table query is very fast, because only one read is required! Const is used to compare a fixed value with a primary key or UNIQUE index. In the following queries, tbl_name is the const table:SELECT * FROM tbl_name WHERE primary_key =

The Fibonacci Sequence, also known as the Golden series. In mathematics, the Fibonacci series are defined as follows by recursive Methods: F0 = 0, F1 = 1, Fn = F (n-1) + F (n-2) (n> = 2, in modern physics, quasi-crystal structure, chemistry, and other fields, the Fibonacci series are directly applied. Now, from an algo

[Problem] 1. Division is not required. Two arrays A [n], B [N], where each element value of a [n] is known, and B [I] is assigned a value, B [I] = A [0] * A [1] * A [2]... * A [N-1]/A [I]; requirements: 1. Division operations are not allowed.
