Does "contiguous" do any work in the first line of the description? Is that actually a requirement somehow?

Hello Lekha Peparthy,

Perhaps the best way to start with Codewars is to do a course in basic Python which is one to the easier languages to learn. Get a feel for how to do things then have a go at very simple problems and build up gradually. Don't be in rush. Despite what others may tell you it takes time to learn how to problem solve. More accurately breaking a problem down into small parts that you can solve and start joining the parts together to form a solution to a problem.

One big advantage of Codewars is being able to see others solutions which I find are nearly always better than mine! But that's a good thing because then you learn a little each day...

Best of luck

Try some easier problems; 8kyu problems will help you better understand the basics.

Other resources to consider:

• MDN
• Free Code Camp

With some practise, you'll be able to understand and solve this problem with ease.

Good luck! :)

i am just beginner and i don't know basics so how can i know about this

It is a pity that the condition does not say that arrays can be of different sizes and they may not exist at all
