Answer:
Read the file and save it to a variable as a string, split the string variable and cast it to a set object using the set function to get the unique words in the file. Then use the max function with the key attribute to use regular expression module "re" to compare the first letter of each item to return in a list comprehension or append to a list.
Explanation:
The open function is used to import a file in python, the split string method splits the string to a list of items and the set function removes any duplicates of a word or item.
Using the for loop statement, iterate over the items and compare and return the items in alphabetical order with the 're' search method getting the item with uppercase letters with higher precedence than lowercase.
Answer:
The Basic Program is as follows:
10 LENGTH = 50
15 WIDTH = 30
20 AREA = WIDTH * LENGTH
25 PRINT AREA
30 END
The Algorithm is as follows:
1. Start
2. Let Length = 50
3. Let Width = 30
4. Compute Area = Length * Width
5. Display Area
6. Stop
See Attachment for flowchart (flowchart is designed using draw io tools)
Explanation:
The flowchart, algorithm and basic program all follow the same sequence and explanation
Using the basic program as a case study;
Line number 10: The program starts by initializing LENGTH to 50
Line number 15: It then initializes WIDTH to 30
Line number 20: The AREA is calculated by LENGTH * WIDTH
Line number 25: The value of AREA is printed afterwards
Line number 30: Lastly, the program stops execution
Answer:
The program in C++ is as follows:
#include <iostream>
using namespace std;
int main(){
int qty;
float discount = 0;
cout<<"Quantity: ";
cin>>qty;
int cost = qty * 100;
{
; }
cout<<"Cost: "<<cost - discount;
return 0;
}
Explanation:
This declares the quantity as integer
int qty;
This declares and initializes discount to 0
float discount = 0;
This prompts the user for quantity
cout<<"Quantity: ";
This gets input for quantity
cin>>qty;
This calculates the cost
int cost = qty * 100;
If cost is above 1000, a discount of 10% is calculated
{
; }
This prints the cost
cout<<"Cost: "<<cost - discount;
