Problem Statement: Write a Python program to store marks scored in subject “Fundamental of Data Structure” by N students in the class. Write functions to compute following:
|
|
a) The average score of class
|
|
b) Highest score and lowest score of class
|
|
c) Count of students who were absent for the test
|
|
d) Display mark with highest frequency
|
|
