Hi,
A Friend is doing maths in University and has had some coursework to do with
python.
The question is
"Write a program that calculates how many positive integers less than N are not
divisible by 2,3 or 5. The user should be prompted to supply the Number N.
Demonstrate your program output when the input N is your student id. (13006517)
"The collatz process is as follows. Take a positive integer n greater than 1.
while n is greater than 1 repeat the following; if N is even halve it and if N is
odd multiply it by 3 and add 1. The (Unsolved) collatz conjecture is that this
process always terminates.
The user should be prompted to supply the number n, and your program should
build the list of values taken by sucessive iteration of the algorithm, and
print it out. For example, if 7 is input your program should print the list
[7,22,11,34,17,52,26,13,40,20,10,5,16,8,4,2,1]
Demonstrate your program output for an input value consisting of the number formed
adding 10 to the last digit of your student id. (13006517)"
Any help would be appreciated
What sort of help are you requesting? We're not in the habit of writing
student assignments for them because they will learn nothing from such
an effort.
Your friend should read the book/lecture-notes/whatever, and make an
attempt on the assignment. If he gets stuck, he may ask a specific
Python question. I'm sure lots of help will follow.
As a side note, these are extremely simple beginner problems, each
requiring only a few lines of code. Any programming class that assigned
these must have included some lectures on the basics of programming.
That's where he should start.
