The use of <span>different control features in the design of the user interface are : </span>Menu bar - displays the main options at the top of the screen.
Toolbar - contains icons that represent shortcuts for executing common commands.
Command button - start an action such as printing a form or requesting Help.
Dialog box - allows a user to enter information about a task that the system will perform.
Text box - display messages or provide a place for a user to enter data.
Toggle button - is used to represent on or off status — clicking the toggle button switches to the other status.
List box - displays a list of choices that the user can select.
Scroll bar - allows the user to move through the available choices.
Drop-down list box - displays the current selection; when the user clicks the arrow, a list of the available choices displays.
Option button - represent groups of options. The user can select only one option at a time; selected options contain a black dot.
nums = list(map(int, input().split()))
mean = sum(nums)/len(nums)
print("The mean is",mean)
values = 0
for x in nums:
values += abs(x - mean)**2
print("The standard deviation is",(values / (len(nums)-1))**0.5)
I wrote my code in python 3.8. I hope this helps.

Answer:
n := length(A)
repeat
swapped := false
for i := 1 to n-1 inclusive do
<em> /* if this pair is out of order */</em>
if A[i-1] > A[i] then
<em> /* swap them and remember something changed */</em>
swap(A[i-1], A[i])
swapped := true
end if ⇒
end for
until not swapped
end procedure
