Problem 1: Define a function RemoveDuplicate(nlist) to remove duplicate elements from list. Here are some examples: [] -> []

[1,2] -> [1,2]

[1,1,2,2,3,3] -> [1,2,3]

Problem 2: Your task is to process a sequence of integer numbers to determine the following statistics:

 o) minimum value
 o) maximum value
 o) number of elements in the sequence
 o) average value

For example:

input = [6, 9, 15, -2, 92, 11]

output:

    o) minimum value = -2
    o) maximum value = 92
    o) number of elements in the sequence = 6
    o) average value = 21.833333
