You must find the solution by yourself, not by reading the discussion. Giving a pattern is giving the solution.

Can someone explain me how to get to 100 in 15 steps I'm also stuck here. 91-14 = 77, 77+15 = 102. How to reach 100 ? Please give a pattern.

Ikr!

tests are fine, you actually can get there in 15 steps, just think about how you can do that

OH!!! It is length vs width. Sorry, my bad :)

If i must get exactly n'th position, then how do i get 100 in 15 steps? It is impossible. because 91 + 14 == 105 and if you move -> or <- by 15 from 105, you can not reach exactly 100. Check Haskell tests please.

The standard width of the rolls he wants to buy is 52 centimeters. The length of a roll is 10 meters.

Square negative number equals square of this number without sign. Jesus Christ.

Too much time killed by 8kyu. Not worth it.

Why not 10 kyu then?

This is not 8kyu. Who approved this kata has to feel guilty.

In Haskell function returns Maybe Int, but test case expects Int. Types don't match. Change test cases so types match.

Still not fixed
