### The Problem

This was more of a string matching exercise followed by a bit of arithmetic on the extracted data. Part 2 involves a bit of logic.

### My Solution

The first thing that came to mind was regular expressions with named fields. Its been a while, so I had to go back to the (excellent) docs, but this was pretty straightforward.

Turns out this was overkill (see below)! Also, I found out not one but two improvements in my `if` statements!

### Other Approaches

There isn’t much to explore in terms of algorithm, since the task isn’t very complicated. So mostly looking at what I could learn from doing differently the

#### Implementation

• My traditional `C` based thinking translated into python: `if(num >= min_inst and num <= max_inst):` A more pythonic way of doing the same: `if(min_inst <= num <= max_inst):`
• I blindly translated the requirements of part 2 into two `if` statements, since we needed to satisfy either of two conditions, but not both …but that’s just what an xor does!
• Another approach that I liked for part 2 was along the lines of `if(condition_1 != condition_2):`
