Lucas is a theoretical physicist turned software developer. He's spent many years writing his own code for models (e.g., running quantum transport simulations) so he understands the natural behavior of code quite well. He can easily adapt to most technologies, given his multidisciplinary experience, and currently, he's focusing on full-stack development projects where he can generate added value.

Experience
K-Dominant Character
The solution uses a binary search which, for this problem, gives a convergence order of O(N*Log(N)) instead of O(N^2) for a naive approach. To run the code, you will need to use the Ruby interpreter. Then, write a random string and press enter. The result will be the minimal length of the substring that satisfies the condition explained above.
