Question 6
Level 2
Question:
Write a program that calculates and prints the value according to the given formula:
Q = Square root of [(2 * C * D)/H]
Following are the fixed values of C and H:
C is 50. H is 30.
D is the variable whose values should be input to your program in a comma-separated sequence.
Example
Let us assume the following comma separated input sequence is given to the program:
100,150,180
The output of the program should be:
18,22,24
Hints:
If the output received is in decimal form, it should be rounded off to its nearest value (for example, if the output received is 26.0, it should be printed as 26)
In case of input data being supplied to the question, it should be assumed to be a console input.

# Selection Sort
# Example 1
# Selection Sort is a sorting algorithm used to sort a data set either in
# incremental or decremental order.
# How does Selection sort work?
# 1. Iterate through the data set one element at a time.
# 2. Find the biggest element in the data set (Append it to another if needed)
# 3. Reduce the sample space to `n - 1` by the biggest element just found.
# 4. Start the iteration over again, on the reduced sample space.
# 5. Continue till we have a sorted data set, either incremental or decremental
# How does the data sample reduces in each iteration?
# [10, 4, 9, 3, 6, 19, 8] - Data set
# [10, 4, 9, 3, 6, 8] - [19] - After Iteration 1
# [4, 9, 3, 6, 8] - [10, 19] - After Iteration 2
# [4, 3, 6, 8] - [9, 10, 19] - After Iteration 3
# [4, 3, 6] - [8, 9, 10, 19] - After Iteration 4
# [4, 3] - [6, 8, 9, 10, 19] - After Iteration 5
# [3] - [4, 6, 8, 9, 10, 19] - After Iteration 6
# [3, 4, 6, 8, 9, 10, 19] - After Iteration 7 - Sorted data set
# Let's check what the Selection Sort algorithm has to go through in each
# iteration
# [10, 4, 9, 3, 6, 19, 8] - Data set
# [10, 4, 9, 3, 6, 8] - After Iteration 1
# [4, 9, 3, 6, 8] - After Iteration 2
# [4, 3, 6, 8] - After Iteration 3
# [4, 3, 6] - After Iteration 4
# [4, 3] - After Iteration 5
# [3] - After Iteration 6
# [3, 4, 6, 8, 9, 10, 19] - After Iteration 7 - Sorted data set
# Observations:
# 1. It takes `n` iterations in each step to find the biggest element.
# 2. The next iteration has to run on a data set of `n - 1` elements.
# 3. Hence the total number of overall iterations would be:
# n + (n - 1) + (n - 2) + (n - 3) + ..... 3 + 2 + 1
# Since `Selection Sort` takes in `n` elements while starting, and goes through
# the data set `n` times (each step reducing the data set size by 1 member),
# the iterations would be:
# n + [ (n - 1) + (n - 2) + (n - 3) + (n - 4) + ... + 2 + 1 ]
# Efficiency:
# We are interested in the worse-case scenario.
# In a very large data set, an `n - 1`, `n - 2` etc.. won't make a difference.
# Hence, we can re-write the above iterations as:
# n + [n + n + n + n ..... n]
# Or also as:
# n x n = n**2
# O(n**2)
# Final thoughts:
# Selection Sort is an algorithm to sort a data set, but it is not particularly
# fast. For `n` elements in a sample space, Selection Sort takes `n x n`
# iterations to sort the data set.

First, a simulation...
Evidently, floor 1 contains all triangular numbers.
Looking on oeis,...
floor 2 contains numbers 2, 7, 9, 16 and then a(n) = 2a(n-1) - 2a(n-3) + a(n-4)
a(1) = 2
a(2) = 7
a(3) = 9
a(4) = 16
floor 3 contains a(0) = 1 then a(n) = n^2 - a(n-1) for n >= 1.
floor 4 contains blah blah blah
it turns out that P(f, r) is something like (r + f)(r + f - 1)/2 + f/2 * (-1)^(r + f).
This formula works for even f, and then for odd ones you have to modify it slightly. Should be evident by the simulation.
Why it works, I have no idea.
Also note that the given number is 2^27 * 3^12. That's how we arrive at the answer.

# # kNN Classification using k-mer frequency representation of text
#
# In this project, we will create a program to transform text into vectors using a slightly different technique than previously learned, and then perform kNN based classification on the resulting vectors. We will be using the badges UCI dataset (https://archive.ics.uci.edu/ml/machine-learning-databases/badges/badges.data), which contains names of some conference attendees along with a "+" or "-" class for each name. We will first make the text lowercase and separate the class from the badge name for each object, e.g., "+ Naoki Abe" should be turned into the object "naoki abe" with class "+". We will keep track of the original name ("Naoki Abe") associated with the vector.
#
# Our program will have two input parameters, c and k. Given the input parameter c, for each name, it will construct a vector of c-mer terms (usually called k-mers, but I am calling them c-mers since the input variable k is being used for kNN) of the required c length, by enumerating all subsequences of length c within the name. For example, if c=3, “naoki abe” becomes < “nao”, “aok”, “oki”, “ki “, “i a”, “ ab”, “abe” >. Finally, we will use the same technique we learned for word-based terms to construct sparse term-frequency vectors for each of the objects.
#
# Using the constructed vectors and their associated classes, given the input parameter k, we will construct a program that should perform kNN based classification using cosine similarity and 10-fold cross-validation and report the average classification accuracy among all tests. The class of the test sample should be chosen by majority vote, with ties broken in favor of the class with the highest average similarity. In the rare case that the test sample does not have any neighbors (no features in common with any training samples), we will assign a predicted class label by drawing a random value from a uniform distribution over [0,1) and classifying the test sample as “+” if the value is greater than 0.5 and “-“ otherwise.
