Project Euler Level 1 GET!

I solved 25/299 problems in Project Euler, which means I achieved level 1 of proficiency!

Through these 25 problems, I actually learned a few things alone the way:

• The properties of prime numbers
• How to do primality test
• How to do prime factorization in programs
• Implemented Sieve of Eratosthenes algorithm
• How to use Python generators
• Encountered dynamic programming problems and solved them
• How to optimize your code through careful inspections
• How to do profiling on your code
• How to reuse existed modules in Python

Good Job Henry!

Played with python module

while I was solving problems in Project Euler. I also implemented an elegant algorithm to find prime numbers - Sieve of Eratosthenes. Kind of fun.

Prime factoring problem

The prime factors of 13195 are 5, 7, 13 and 29. What is the largest prime factor of the number 600851475143 ?
