Integer factorization (conversion) Compared with prime number determination, the implementation of Factorization cannot be so fast. There is still no polynomial algorithm similar to the prime number determination for factorization, which also ensures the security of RSA public key systems.The basis of the fault. Given the difficulty of these two problems, it is

Title: Decompose a positive integer into factorization. For example: Enter 90 and print out 90=2*3*3*5. Analysis: To decompose n factorization, you should first find a minimum prime number k, and then complete the following steps: (1) If the prime number is exactly equal to N, then the process of decomposing the factorization is finished and printed

In the Nnet series, The Matrix factorization feels strange, but after listening to the first section of the course it becomes clear.Lin first introduced a difficult problem in machine learning: categorical featuresThe problem is characterized by some kind of ID number, not numerical.If you want to handle this situation, you need encoding from categorical to numericalOne of the most common encoding methods is binary vector encoding (which is also used

Topic content:Each non-prime (composite) can be written as a number of primes (also known as prime numbers) in the form of multiplication, and these primes are called the composite's mass factor. For example, 6 can be decomposed into 2x3, and 24 can be decomposed into 2x2x2x3.Now, your program reads an integer in a [2,100000] range, then outputs its mass factorization, and when it reads a prime number, it outputs itself.Input format:An integer that is
