The relationship between iterable, iterator and generator
First, the concept of grammatical
PHP5.5 introduces the concept of an iterative generator, the concept of iteration is already in PHP, but the iterative generator is a new feature of PHP, similar to the iterative generator in Python3, to see how the PHP5.5 Iteration Builder is

Description
For a positive integer n, the digit-sum of n are defined as the sum OfN itself and its digits. When
Python3 digit Number (6), python3 digit number
The Python numeric data type is used to store numeric values.
The data type cannot be changed, which means that if you change the value of the numeric data type, the memory space will be
The only order number generation thinking in high concurrency.
Order No. 3 properties: 1. Uniqueness 2. Non-speculative 3. EfficiencyOptional Option One
This scenario uses the current time, including the number of milliseconds, the number of
1. Question
Given a random number generator, this generator can generate a random number ranging from 1 to 5 () evenly. How can we use this generator to generate a number ranging from 1 to 7?
2. Ideas
Method 1: generate two (1, 5) random numbers.
RandomThe random class in Java generates a pseudo-random number, uses the seed of 48-bit, and then calls a linear congruential formula linear congruence equation (Donald Knuth's programming Art of 3.2.1)If two random instances use the same seed, and
In the previous blog, we learned about the real random number generator based on physical phenomena, however, the real random number generation is slow, for the actual computation needs, the random number in the computer is generated by the program
Method One: Generate two (1,5) random number, this is a total of 25 cases, note that the two numbers are in order, from the 25 cases, take the first 21, each three kinds of representative (1,7) A number, if you take the case of the 21, discard the
