From Fibonacci Sequence to Tower of Hanoi: Recursive Thoughts in Programming Python Learning Mathematics
The idea of recursion in programming refers to a method of solving problems that uses functions to call their own characteristics and decompose a complex problem into smaller sub-problems until the sub-problems can be solved directly. The advantage of recursion is that it can make the code concise and clear, and it is suitable for […]

Java number processing class–Math class–big number operations
Operation classes for large numbers in Java: java.math.BigInteger java.math.BigDecimal 1.BigInteger class The maximum value of Int is 2^31-1. If you want to handle larger numbers, you must use BigInteger. The BigInteger class provides addition, subtraction, multiplication, division, absolute value, opposite number, greatest common divisor, and judgment. For prime numbers and other methods. Using the BigInteger […]

#台云integration#SHOW out your meta-service#boringmathematics
1. Why is there boring mathematics No matter what the reason is, people’s time is becoming more and more fragmented, and even more so, the fragmentation of time has become the normal life of some people. Sporadic time fragments often make people feel bored. Apart from mindlessly watching short videos, can you do something more […]

Optimization modeling ideas and sample code for the “deoxidation alloying” batching plan for molten steel in Question D of the 2019 MathorCup College Mathematical Modeling Challenge
One topic Deoxidation and alloying during the steelmaking process is an important process step in steel smelting. For different steel types, different amounts and types of alloys need to be added at the end of smelting to ensure that the alloy elements contained in them meet the standards, and ultimately the finished steel meets specific […]
