Some innovations of teaching the course on Data structures and algorithms

The teaching of practical foundations of computer science is still a big challenge. The course on Data Structures and Algorithms is one of the most important foundational courses that are necessary to be included in the curriculum of future IT experts. The content of this course is quite wide and it differs in many universities. In our teaching process, we identified some interesting problems that could be presented more attractively - using the visualizing software. In this paper, we present a purpose, rôle, design and methodology of our developed software tool for the convenience of teaching and studying the problem of the longest common subsequence.
