Mountain Ranges and Motzkin Paths

U ovom radu obrađeni su Catalanovi, Motzkinovi i Narayanini brojevi, te Dyckovi putevi. Pokazali smo da su Catalanovi brojevi niz brojeva. Catalanove brojeve smo koristili kao uvod u Dyckove puteve, te Dyckov jezik. Pokazali smo kako je broj Dyckovih puteva duljine n jednak Catalanovom broju Cn. Uveli smo i Naranayine brojeve koji određuju broj Dyckovih puteva duljine n s k vrhova. Zadnji pojam bili su Motzkinovi brojevi koji određuju broj istoimenih puteva. Uz to, napravljen je i računalni program koji računa i iscrtava Motzkinove i Dyckove puteve.This paper is about Catalan, Motzkin and Narayana numbers, as well as Dyck paths. We have shown that Catalan numbers are a sequence. Catalan numbers have been used as an introduction to Dyck paths and the Dyck language. We have shown that the number of Dyck paths for a certain n is equal to the Catalan number Cn, and that the number of Dyck paths for a certain n with k peaks is equal to the Narayana number N(n, k). The last term we introduced was Motzkin numbers, which count the number of paths with the same name. In addition to that, a computer program has been written that counts and draws Motzkin and Dyck paths
