One way to avoid Runge's problem is to choose non-equally spaced data points. A particularlygood set to choose are the so-called Chebyshev nodes. To use these, replace the equidistant pointsxk produced by xeqwithxk = COS2k+12n+2for k=0,..., n.(3.4)Generate data points using (3.4) and (3.3), then plot the resulting Lagrange interpolating polynomialand, hence, show that using (3.4) solves the Runge problem.

With python please, f(n) = f(1) + f(2) + ... + f(floor(sqrt(n))), for n>=3 f(1) = 2, f(2) = 5, f(3) = 7 (a) Implement 3 functions for this recurrence relation, one for each of the approaches. (b) Run the 3 functions for different n values and time their runtime and describe what you see. (c) How is the pattern of runtimes different here than for the Fibonacci problem? Can you explain why?
For the one-dimensional version of the closest-pair problem, i.e., for the problem of finding two closest numbers among a given set of n real num- bers, design an algorithm that is directly based on the divide-and-conquer technique and determine its efficiency class. Is it a good algorithm for this problem?
illustrates the procedure for Fibonacci search. Here n, thenumber of data elements is such that: i) Fk+1 > (n+1); andii) Fk + m = (n +1) for some m ≥ 0, where Fk+1 and Fk are two consecutiveFibonacci numbers.
PLEASE USE PYTHONGiven a jungle matrix NxM:jungle = [ [1, 0, 0, 0], [1, 1, 0, 1], [0, 1, 0, 0], [1, 1, 1, 1,]]Where 0 means the block is dead end and 1 means the block can be used in the path fromsource to destination.Task:Starting at position (0, 0), the goal is to reach position (N-1, M-1).Your program needs to build and output the solution matrix – a 4x4 matrix with 1’s inpositions used to get from the starting position (0,0) to the ending position (N-1,M-1)with the following constraints:You can only move one space at a timeYou can only in two directions: forward and down.You can only pass thru spaces on the jungle matrix marked ‘1’If you cannot reach the ending position – print a message that you’re trapped in thejungleAlgorithm:If destination is reachedprint the solution matrixElseMark current cell in the solution matrixMove forward horizontally and recursively check if this leads to a solution If there is no solution, move down and recursively check if this leads to a solution If…
Run mergesort for large random arrays, and make an empirical determination of the average length of the other subarray when the first subarray exhausts, as a function of N (the sum of the two subarray sizes for a given merge).
Show L = { w | w is an element of {0, 1, 2}* and (the number of 0s in w ≥ the number of 1s in w) and ((the number of 0s + the number of 1s in w) divides the number of 2s in w) } is not context free. You should assume that p is the pumping length and for any string s in L with |s| ≥ p, s can be broken into 5 pieces, s = uvxyz.
You are given k > 2 linked lists, each containing n > k natural numbers sorted in increasing order. All n · k numbers in these lists are distinct. Describe an algorithm that finds the k-th smallest element among all n k numbers. Your algorithm should run in O(k log k) time. Analyze the running time of your algorithm and prove its correctness.
Consider a Skip List with n nodes. Each node k has a random "height" hg, which is the number of linked lists that includes node k. The heights nodes are statistically independent, where P[hx = m] = 2-m, for m 2 1 and P[h = m] = 0 , for m m] 0 such that P[H > m] <= for m = c log, n
Give a MPI program segment to convert a n-by-n matrix distributed on a n-by-n 2D mesh such that allits rows and columns get sorted in ascending order. Show only the iterative loop. Only communicationsallowed are to the four direct neighbors. (Hint: You may employ a variant of odd-even transpositionsort, but the whole matrix does not need to be sorted.)
