Weird recursion tree analysis. Suppose we have an algorithm that on problems of size n, recursively solves two problems of size n/2, with a “local running time” bounded by t(n) for some function t(n). That is, the algorithm’s total running time T(n) satisfies the recurrence relation T(n) ≤ 2T(n/2) + t(n). For simplicity, assume that n is a power of 2. Prove the following using a recursion tree analysis (a) If t(n) = O(n log n), then T(n) = O(n(log...

REAL ANALYSIS Question 1 (1.1) Let A be a subset of R which is bounded above. Show that Sup A E A. (1.2) Let S be a subset of a metric space X. Prove that a subset T of S is closed in S if and only if T = SA K for some K which is closed in K. (1.3) Let A and B be two subsets of a metric space X. Recall that A°, the interior of A,...

2, For each of these sets. A={3n : n E N), B = {r E R : x2 < 7), and C = {x E R : x < 12), (i) Is the set bounded above? Prove your answer.] ( .] ii) Is the set bounded below? Prove your answer answer the following questions:
1. a) Let A = {2n|n ∈ ℤ} (ie, A is the set of even numbers) and define function f: ℝ → {0,1}, where f(x) = XA(x) That is, f is the characteristic function of set A; it maps elements of the domain that are in set A (ie, those that are even integers) to 1 and all other elements of the domain to 0. By demonstrating a counter-example, show that the function f is not injective (not one-to-one). b)...
