Question

State True or False. i) Binary search is used for searching in a sorted array. AND ii) The time complexity of binary search is O(log n). A) True, False B) False, True C) False, False D) True, True Explain

Answer #1

D) TRUE,TRUE.

i) Binary search searcha sorted array by repeatedly dividing the search interval in half .If the value of the search key is less than the item in the middle of the interval ,narrow the interval to the lower half.Otherwise, narrow it to th eupper half.Repeat the steps and check untill the value is found or the interval becomes empty.

ii) The time Complexity of Binary search is O(log n)

Select All true answers about linear and binary search
1. The advantage of linear search is that it runs in O(1) space
complexity and binary search can only run in O(logn) space
complexity
2. The disadvantage of binary search is that it requires the
container to be sorted which linear search does not.
3. The advantage of binary search over linear search is that is
more efficient O(logn)versus O(n) average/worst case).
4. The advantage of linear search is that it...

Assume that we have a sorted array a[n]with n non-negative
numbers.
a. Develop an algorithm using divide-and-conquer to search for
an element x in this sorted array a[n]. This algorithm will take an
input of a sorted array a[n], and return the index of element x is
an element of a[n], or return -1if xis NOT an element of this
array.
b. Analyze the time complexity of this algorithm.

how to pass in an object from an array of objects in a binary
search on swift? I have the following:
func binarySearchPrefix(array: [String], target:
String) -> Bool {
var left = 0
var right = array.count
- 1
while (left <= right)
{
let mid = (left + right) / 2
let value = array[mid]
if (value.hasPrefix(target)) {
return true
}

In C++, given an array of strings(assume the array is sorted
lexicographically), and an input prefix, how would I return all the
words that start with the given prefix. (must use binary search for
searching)
For example, given the following array, if user were to input,
"Can" our output would be
Words that start with "can" are :
Candy Bars
Candy Buttons
Candy Melts
Candy Props
Candy Sprinkles
Candy Sticks
