Question

Given a list of n integers, find all elements of the list for which there exist exactly one element of the list which is twice that number. What is the question?

a) Determine the median of the given list.
b) Find the mean of the list and its impact on doubling.
c) Identify the elements satisfying the given condition.
d) Analyze the distribution of even and odd numbers in the list.

Answer 1

To find the elements in a list for which there exist exactly one element that is double that number, iterate through each element and check if there is exactly one element in the list that is double the value of the current element.

Step-by-step explanation:

The subject of this question is to identify the elements of a given list for which there exist exactly one element that is twice that number. In other words, we need to find the numbers in the list that have a unique doubling number.

To solve this question:

1. Iterate through each element of the list.
2. For each element, check if there is exactly one element in the list that is double the value of the current element.
3. If there is, add the current element to the solution.

For example, given the list [1, 2, 3, 4, 5], the solution would be [1, 2, 4].
