Other data structures would also be able to accommodate similar data. In Python, a similar object with better language support would be a list of lists. However, a list of lists cannot always represent the merg

The parser we will write handles expressions that include numbers, parentheses, and the operators + and *. We assume that the input string has already been tokenized into a Python list. The token list for (3+7)*9 is: ['(', 3, '+', 7, ')', '*', 9, 'end'] The end token...
Some data structures (e.g. TreeMap, TreeSet) require a comparator function to automatically keep their elements sorted upon insertion. This comparator is necessary during the initalization. Comparator is defined as: Return values (int): negative , if a < b zero , if a == b positive , if...

An evaluation on tree representations of pseudoknotted RNA secondary structures and acyclic molecular graphs shows that both exact and approximate (normalized) EPS better preserves functional similarities between the compared RNAs and molecules than the often-used TED. Python implementations of our ...
