Plan to work on the medium level algorithm called "Maximum Gcd and Sum".
Analysis and investment of time
It is running late for Julia to work on week of code contest. Julia read all discussions and this medium algorithm only has single digit successful rate after a few days.
Julia likes to do some research to help herself to solve the problem. She could not afford to spend a few hours without gaining some new skills.
She decides to work on a few related algorithm first.
First one is called "Efficient program to print all prime factors of a given number".
Plan to read the topcoder article called "Prime numbers, factorization and Euler function".
