2.4 Code Practice: Question 2 Write a program that accepts a number as input, and prints just the decimal portion. Your program should also work if a negative number is inputted by the user.

Sample Run
Enter a number: 15.789
Sample Output
0.789
Hints:
You'll likely need to use both the int() and float() commands in your program.
Make sure that any number the user inputs is first stored as a float.
You'll need to use at least two variables in your program: one that stores the original value entered by the user, and one that represents the integer value entered by the user.
These two variables can be subtracted from one another, to leave just the decimal portion remaining.
Don't forget to have your program print the decimal portion at the end!

Some of your friends have gotten into the burgeoning field of time-series data mining, in which one looks for patterns in sequences of events that occur over time. purchases at stock exchanges"what's being bought" are one source of data with a natural ordering in time. given a long sequence s of such events, your friends want an efficient way to detect certain "patterns" in them"for example, they may want to know if the four events buy yahoo, buy ebay, buy yahoo, buy oracle occur in this sequence s, in order but not necessarily consecutively. they begin with a collection of possible events (e.g., the possible transactions) and a sequence s of n of these events. a given event may occur multiple times in s (e.g., yahoo stock may be bought many times in a single sequence s). we will say that a sequence s is a subsequence of s if there is a way to delete certain of the events from s so that the remaining events, in order, are equal to the sequence s . so, for example, the sequence of four events above is a subsequence of the sequence buy amazon, buy yahoo, buy ebay, buy yahoo, buy yahoo, buy oracle their goal is to be able to dream up short sequences and quickly detect whether they are subsequences of s. so this is the problem they pose to you: give an algorithm that takes two sequences of events"s of length m and s of length n, each possibly containing an event more than once"and decides in time o(m + n) whether s is a subsequence of s.

Write the pseudo code for this problem based on what you learned from the video. the purpose is to design a modular program that asks the user to enter a distance in kilometers, and then converts that distance to miles. the conversion formula is as follows: miles = kilometers x 0.6214

Why would a business likely use a java applet - to back up their data files for the business - to create a program that a customer can launch in their web browser - to create music on a powerpoint presentation - to organize files on their company directory
