What is the python syntax for taking the natural logarithm of variable x? Include the library name in the syntax.

Please Answer in C++ only A Rajesh teaches a cooking class. The course is attended by NN students, numbered 11 to NN. The cook must participate in the presence before each class, i.e. call out the names of the students one by one and indicate which students are present. Each student has a first and last name. To save time, Rajesh only wants to call up students' first names. However, if there are multiple students with the same first name, the Rajesh must call out the full names (first and last names) of all those students. For any student who does not share a first name with any other student, the cook can still only call that student's first name. Help the Rajesh decide for each student whether to call that student's full name or just their first name. Input 1 1 hasan jaddouh Output hasan
