In python, how do you generate a distance matrix H where in each entry hij, the distance between row i and row j are stored, distance is computed by the inner product <x,y>C := xTCy, where the matrix C is a 3x3 matrix: [3 1 6 1 2 1 6 1 27]. The dataset is a 26x5 matrix and I need to find the distance using the above inner product between each row - I should end up with a 26x26 distance matrix H, where each diagonal entry (i=j) is 0.
For input vector x, write a function to check whether there exists at most 5 elements in x whose values are less than 7.
Question 2: Encoding Cryptography is the study of trying to create secure information by obscuring the original message. One simple encryption method is to substitute letters from the original message with other letters. To make it harder to decrypt the hidden message, we may also remove clues such as the length of the words in the message and any punctuation or capitalization. Write a function encode that consumes a string message. The function produces a string which is encrypted according the following procedure: • Only the letters from the original message will be encrypted. Other characters such as spaces, punctuation, numeric digits, etc. are not included in the encrypted message at all. • The encrypted message will only contain uppercase letters. • Each letter will be replaced by the uppercase letter at the opposite end of the English alphabet. In other words, A or a will become z, B or b will become Y, C or c will become x, .., z or z will become A. • The encrypted message will…

Question : Imagine that you track your commute times for (10 days) and recorded your observations in minutes as {17, 16, 20, 24, 22, 15, 21, 15, 17, 22}. Enter your observations into a series (vector) in Python and label it 'data'. Next answer the following questions: ● How many times were your commute 20 minutes or more? Hint: Write a condition! What percent of your commutes are less than 17 minutes?
Ensure that the input values representing fractions are stored with denominators that are positive integers. It doesn't require the user to only enter a positive denominator value; the user should not be inconvenienced by such a restriction. For example, whilst values of 1 / -2 are acceptable inputs for a fraction, the output representation should be -1 / 2. Solution should check the denominator input; if it is negative, swap the sign of both numerator and denominator instance variables. Test this functionality with TestFraction class. //Import the essential package import java.util.ArrayList; import java.util.Scanner; //Define the class Fraction class Fraction { //Declare the variables to store the numerator and denominator private int n, d; //Define the default constructor public Fraction() { //Initialize the values this.n = this.d = 0; } //Define the parameterized constructor public Fraction(int n, int d) { //Initialize the variables this.n = n; this.d = d; } //Define the getter…
In mathematics, Pascal's triangle is a triangular array of the binomial coefficients that arises in probability theory, combinatorics, and algebra. 1 1 1 1 12 1 1 3 2+1 1 Formula for Pascal's triangle is given by: n! 1 k! (n − k)! - where in denotes a row of the triangle, and k is the position of a term in the row. Create a function which takes a number and returns n top rows of Pascal's Triangle flattened into a one-dimensional list. Examples → pascals_triangle (1) [1] pascals_triangle (2) [1, 1, 1] pascals_triangle (4) → RUBY [1, 1, 1, 1, 2, 1, 1, 3, 3, 1]
