Imagine a bunch of pairwise distinct integer numbers a[0], a[1] , ..., a[n - 1] placed on a circle in the same order. There are n pairs of neighboring numbers: (a[o], a[1]) (a[1], a[2]). (a[n - 2], a[n - 1]), (a[n 1], a[0]) 1 2 3 4 } You tried to encode the circle of numbers by recording the pairs, but unfortunately the numbers in these pairs got shuffled, so now each pair (x, y) could be represented either as (x, y) or (y, x). You are given an array pairs of these shuffled pairs, and your task is to return the initial state of the numbers on the circle. Please, note that any cyclic rotation of the initial state is also considered to be a correct

1. package newton’s method for approximating square roots (case study 3.6) in a function named newton. this function expects the input number as an argument and returns the estimate of its square root. the script should also include a main function that allows the user to compute square roots of inputs until she presses the enter/return key. 2. convert newton’s method for approximating square roots in project 1 to a recursive function named newton. (hint: the estimate of the square root should be passed as a second argument to the function.) 3. elena complains that the recursive newton function in project 2 includes an extra argument for the estimate. the function’s users should not have to provide this value, which is always the same, when they call this function. modify the definition of the function so that it uses a keyword parameter with the appropriate default value for this argument, and call the function without a second argument to demonstrate that it solves this problem. 4. restructure newton’s method (case study 3.6) by decomposing it into three cooperating functions. the newton function can use either the recursive strategy of project 1 or the iterative strategy of case study 3.6. the task of testing for the limit is assigned to a function named limitreached, whereas the task of computing a new approximation is assigned to a function named improveestimate. each function expects the relevant arguments and returns an appropriate value. 5. a list is sorted in ascending order if it is empty or each item except the last one is less than or equal to its successor. define a predicate issorted that expects a list as an argument and returns true if the list is sorted, or returns false otherwise. (hint: for a list of length 2 or greater, loop through the list and compare pairs of items, from left to right, and return false if the first item in a pair is greater.)

Brian wants to conduct an online search with a certain phrase. he intends to use the words books that belong to the 1800s in his search. how should he use the word that in his search?
