I've solved the meaty bits of this bioinformatics problem, albeit a bit clumsily I think. In particular I've messed around with manipulating the fasta info into a form Biopython's SeqIO.parse() will accept and it screams to be optimized.
So there is my question to you. How can I better save the...
Could I be using fewer variables to make this code look cleaner? Specifically the index1,2,3 variables, I want to find a way to eliminate those variables and use a array[max1] instead however my prgram crashes when I try that.

So I am trying to make my program ask these questions, and this is the code that I have written for it to do so.

For taking part in a course, I need to learn some Java. Unfortunately they only teach Java 1.6, so I understand that later versions could simplify the below code a lot, but I have to stick with 1.6 though, at least for the course.

We recently explored how wealthy countries (those defined as high-income by the World Bank) tend to visit a different set of technologies than the rest of the world. Among the largest differences we saw was in the programming language Python. When we focus on high-income countries, the growth of Python is even larger than it might appear from tools like Stack Overflow Trends, or in other rankings that consider global software development.
In this post, we’ll explore the extraordinary growth of the Python programming language in the last five years, as seen by Stack Overflow traffic within …
