• Roman Numerals Kata
  • Things that I applied or learnt along the journey that led to the final solution -
  • Approach the problem in small steps. I was solving this kata for the first time, I didn't know of any pattern whatsoever initially, hence took this problem, one step at a time and it eventually helped me get to solution. Often times one worries about the end solution or just the destination, without traveling the journey bit by bit.
    • I know you may think this approach(solving for one test at a time as done in this commit and this one) wouldn't give you the desired solution that'll satisfy all cases, but trust me it will help you eventually get there. That's why this approach is worth it.
• Used the older hash syntax in ruby s
