Python Day 10 Leap Year I have a friend Cindy, she was actually born on Feb.29th, and I remember we celebrated her birthday together 2012 in the Maths place! Leap Year was adapted in Gregorian Calendar.  There are Three Criteria:

Linear Diophantine Equation1

In Number Theory Class, Dr.Cavior told us a real story,  One Sunday morning 🌞, he just made a cup of freshly brewed coffee☕ and started to read a book 📒, then he got a call from a friend ☎. The friend was asking for his help with a 1 Million Dollars McDonald’s Puzzle that she was trying for couple days! 

Python Little Goal 3

Python Day 9 Today we will try the basic Arithmetic Operators including , + , – ,* ,/ and squares in Python. Arithmetic Operators: The first line contains the sum of the two numbers. The second line contains the difference of the two numbers (first – second). The third line contains the product of the two numbers. The fourth line…

Geometric Series with Python

Background Story : There were a couple of mathematicians went to a bar, the first guy ordered one beer, the second guy asked for 1/2 of a beer, the third guy asked for 1/4 of a beer, the fourth ordered 1/8 of a beer, and so on… The hot bartender rolled her eyes, poured two beers, and says, “Here, you…

The Chinese Remainder Theorem

Chinese Remainder Theorem  Background Story: back in the Han dynasty, there is a  famous General Han Xin. In order to prevent the spy in the army to detect the number of his soldiers, he used an advanced Counting System (韩信点兵).  Instead off directly counting from 1 to n, he asked his soldiers to number off from 3 times. First time 1…

Python Day 7 Problem 1: Given an array of integers, find the sum of its elements. For example, if the array ar=[1,2,3] , so return 6 . Solution: import math ar=[1, 2, 3, 4, 10, 11] def simplesumarray(ar): return(sum(ar)) simplesumarray(ar) 31   Problem 2: Given the meal price ( meal), tip percent (tip), and tax percent ( tax) for a meal, find and print the meal’s total integer cost: Solution:…

Linear Optimization with Python 2

  Python Day 6: Linear Optimization with Paper Company Last time we did a Pirelli Glass Linear Optimization, it considered a simple problem, because it has only 2 variables.What should we do if there are more variables and with much more complexed constrain systems? Problem: Nancy Grant is the owner of Coal Bank Hollow Recycling company, there is two Recycling Process.

Linear Optimization with Python 1

Python Day 5: Linear Optimization problem  Side Story:  Excel Solver is an excellent tool for Linear Optimization problems, but we need to pay for this platform. In addition, 5 asked me with an extremely surprised facial expression: “What kind of data scientists would use Excel? “ 😱😱😱 Therefore we will introduce how to use Python to solve a Linear Optimization Problem,…
