Here is a program, written in pseudocode, which determines the biggest number in an array:
DECLARE biggest, i : INTEGER
DECLARE arr : ARRAY[1:10] OF INTEGER
arr ← [34,23,65,435,34,56,67,454,34,2]
#remember that in pseudocode the first index in an array is 1
biggest ← arr[1]
FOR i ← 2 TO 10
IF arr[i] > biggest
THEN
biggest ← arr[i]
END IF
END FOR
OUTPUT biggest
Resdesign the program so that a procedure called displayBiggest processes an array that is sent as a parameter.
The following computer program should work after your solution has been written and tested:
DECLARE nums : ARRAY[1:10] OF INTEGER
nums ← [34,23,65,435,34,56,67,454,34,2]
CALL getBiggest(nums)
Note: the function design should include 1 parameter
A computer program stores an array of city names followed by a 2-digit continent code eg:
["london-eu", "madrid-eu", "new york-us", "sydney-au", "santiago-sa", "rome-eu", "bangkok-as", "tokyo-as"]
The program calls a procedure with the following header:
PROCEDURE countCountries(cities : ARRAY[0:n] OF STRING)
where n is the last index of the array.
The procedure produces a count of cities in Europe, USA and Asia and displays the result.
Implement this procedure.
Test your procedure with this test file:
Here is part of a lottery computer program written in pseudocode. It is quite tricky! It uses a global variable.
The program draws 6 lottery numbers in the range 1-49. No two numbers are the same!
To solve this problem in Python, you will have to research how to change data stored in a global variable if you are accessing the variable from a procedure.
Talk to your teacher or classmates if you do not get this.
Here is the pseudocode of the main program:
#array to store 6 lottery numbers, global variable
lottery ← [-1,-1,-1,-1,-1,-1]
drawNums()
FOR i ← 1 TO LENGTH(lottery):
OUTPUT lottery[i]
END FOR
Here is the pseudocode for the procedure drawNums()
PROCEDURE drawNums():
index ← 1
WHILE index<6 DO
x ← RAND(1,49)
alreadyDrawn ← FALSE
FOR i ← 1 TO LENGTH(lottery):
IF x = lottery[i] THEN
alreadyDrawn ← TRUE
END IF
END FOR
IF alreadyDrawn = FALSE THEN
lottery[index]←x
index←index+1
END IF
END WHILE
Code this program in Python.
Note: array indexes in pseudocode start with 1, and in Python they start with 0.
