Zastanawiałeś się może kiedyś w jaki sposób biblioteki do wyrażeń regularnych wyszukują wzorce w teksie? Jeżeli tak to ten artykuł jest dla Ciebie. Uprzedzam kod w Javie, ale tym lepiej bo algorytm i tak warto napisać samemu żeby lepiej zrozumieć :D

Let's assume you are considering using Cassandra for logs storage or in general, for time series storage. You are well prepared - asked google extensively. Yet, there is a trap waiting to kill your cluster in few weeks after lunch.

Dynamic Programming is considered as one of the hardest methods to master, with few examples on the internet. Let's contribute a little with this post series. Today I will cover the first problem - text justification. Credits: MIT lectures.
