In the f(n) = Θ(n)term, let the constants for Ω(n) and O(n)be n0,c0 and c1, respectively In other words, let for all n ≥n0, we have c0n ≤f(n) ≤c1n •First, we show T(n) = O(n) For the base case, we can choose a sufficiently large constant d1 such that T(n) < d1nlgn For the inductive step, assume for all k < n, that T(k) < d1nlgn114 (c) Prove (A\B)∪(B \A) = (A∪B)\(A∩B) Proof Let x ∈ (A \ B) ∪ (B \ A) Then x ∈ A \ B or x ∈ B \ A In the first case, this implies x ∈ A and x /∈ B From this we get x ∈ A or x ∈ B (since the first of those statements is true), so x ∈ A ∪ B We alsoC S A M B I F T H O R S T A I I N O X F R E O C C U P I E D D I N A S H J O N E A F W E L U T C E R E B E L G I I E R U N W A Y U W S P K L O E E Z W U D I N G P A R S B O R T O P O Airports and Air Travel Below are 18 words that begin with the following letters P BOARD
N(t) NX(t)1 j=1 X j By the Strong Law of Large Numbers (SLLN), both the left and the right pieces converge to E(X) as t!1 Since t=N(t) is sandwiched between the two, it also converges to E(X), yielding the rst result after taking reciprocals For the second result, we must show that the collection of rvs fN(t)=t t 1gisProblem 4 Suppose that (x n) is a sequence in a compact metric space Xwith the property that every convergent subsequence has the same limit x2X Prove that x n!xas n!1 Solution Suppose that (x n) does not converge to xThen there exists(c) False The same counterexample applies 3 27) For each of the following six program fragments (a) Give an analysis of the running time (BigOh will do) (b) Implement the code in the language of your choice, and give the running time for several values of N (c) Compare your analysis with the actual running times
