Explanation of Solution

Given:

It is given that in n-element array, the Algorithm D calls the Algorithm E on each element X[i] and the algorithm E runs in O(i) time.

Worst case running time:

The worst case running time measures the resource required in the algorithm. While calculating the running time it takes the input size of “n” to calculate the algorithm. This running time is referred as worst case running time.

  • Since, the algorithm E depends on the “i” value and it executes in O(i) time then it is linearly proportional to i.

i=1ni

From the above expression, the time complexity of algorithm E for each value of X[i] is

4 points Given an n-element array X of integers, Algorithm A executes an O(n3.4)-time computation for each even positive number in X, an Oin2.3-time computation for each odd positive number in X, and an O(n2.5)-time computation for each negative number in X. What are the best-case and worst-case running times of Algorithm A? Justify your answer. For the toolbar, press ALT+F10 (PC) or ALT+FN+F10 (Mac) BIUS Paragraph V Arial 10pt EVE 2 IXO QFS3E
Let T be a sorted array of n elements. An element x is said to be a majority element in T if the number of elements i, with T[i] = x, is greater than n/2. Give an algorithm (code or pseudo-code) that can decide whether T includes a majority element (it cannot have more than one), and if so, find it. Your algorithm must run in linear time.
