Average and Numbers Greater than Average in Array
Average and Numbers Greater than Average in Array
Description:
Given an array arr[] of integers, calculate the average of the array and find and print the numbers greater than the average.
Example 1:
Input: Array = {10, 20, 30, 40, 50}
Output:
Average: 30.0
Numbers greater than average: 40, 50
Example 2:
Input: Array = {-10, 5, 0, -9, 18, 27, -36}
Output:
Average: 0.0
Numbers greater than average: 5, 18, 27
Constraints:
The array length |arr| is at least 1 and at most 10^5.
