Each of them are either well versed in a topic or they are not. The solution is to count occurences of words in both, magazine and ransom. The Question can be found in the Algorithm domain of Hackerrank. Python is a fully object-oriented language like C++, Java, etc. Input Format The first line contains an integer T which denotes the number of test cases. If the length is even the print the word. The second line contains space separated roll numbers of those students. I am trying to solve Determining DNA Health challenge from Hackerrank using python. For example ord('B') returns 66 which is a unicode code point value of character 'B'. This package provides a multiset implementation for Python.. A multiset is similar to the builtin set, but it allows an element to occur multiple times.It is an unordered collection of element which have to be hashable just like in a set.It supports the same methods and operations as set does, e.g. For reading about classes, refer here.
