In order to fulfill my dream, I will organize the lecture notes, homework,  projects from Harrisburg University . Meanwhile, I will publish some data analysis related topics. 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… 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 Little Goal 2

Python Day 8 Problem 1: Factorial  Write a factorial function that takes a positive integer,  N as a parameter and prints the result of  N! Solution: def factor(n): a=1 for i in range (1,n+1): a=a*i print(a) factor(3) 6 factor(5) 120   Problem 2: Age Create a function age() should perform the following conditional actions: If n is between 0 to 12, print Young. If 13 and 19,… Python Little Goal 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:…
