Complexity Analysis
Initialize variables for minimum, maximum, mean, mode, and median.
Traverse the
count
array from the start to find the minimum (first non-zero element).
Traverse the
count
array from the end to find the maximum (last non-zero element).
Calculate the total sum and count of elements in the sample for the mean.
Identify the mode by finding the element with the highest count.
Calculate the median by accumulating counts and finding the middle element(s).
If the total count is odd, the median is the middle element.
If the total count is even, the median is the average of the two middle elements.
Return the statistics as an array
[minimum, maximum, mean, median, mode]
