(Euclidean Distance) Write a program called distance. py that accepts n (int) as command-line argument, two n-dimensional lists x and y of floats from standard input, and writes to standard output the Euclidean distance between two vectors represented by x and y. The Euclidean distance is calculated as the square root of the sums of the squares of the differences between the corresponding entries. . >_*/workspace/project3 $ python3 distance. py 5 -9 1 10 -1 1 -5 9 6 7 4. 13.0 distance. py import math import stdio import sys # Read n (int) from command line. # Read n floats from standard input and store them in a list x. for i in range (...): # Read n floats from standard input and store them in a list y. y = ... for i in range (...): # Set distance to 0.0. # Compute the squared Euclidean distance between x and y. for i in range (...): # Add square of (x[i] - y[i]) to distance. # Set distance to the square root of itself. # Write distance to standard output.

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 even~s--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
