Answer:

void printUniquedWords(char filename[])

void printUniquedWords(char filename[]) {

void printUniquedWords(char filename[]) { // Whatever your t.text file is

fstream fs(filename);

fstream fs(filename); map<string, int> mp;

fstream fs(filename); map<string, int> mp; // This serves to keep a record of the words

string word;

string word; while (fs >> word)

string word; while (fs >> word) {

string word; while (fs >> word) { // Verifies if this is the first time the word appears hence "unique word"

if (!mp.count(word))

if (!mp.count(word)) mp.insert(make_pair(word, 1));

if (!mp.count(word)) mp.insert(make_pair(word, 1)); else

if (!mp.count(word)) mp.insert(make_pair(word, 1)); else mp[word]++;

if (!mp.count(word)) mp.insert(make_pair(word, 1)); else mp[word]++; }

if (!mp.count(word)) mp.insert(make_pair(word, 1)); else mp[word]++; } fs.close(); // Traverse map and print all words whose count

if (!mp.count(word)) mp.insert(make_pair(word, 1)); else mp[word]++; } fs.close(); // Traverse map and print all words whose count //is 1

if (!mp.count(word)) mp.insert(make_pair(word, 1)); else mp[word]++; } fs.close(); // Traverse map and print all words whose count //is 1 for (map<string, int> :: iterator p = mp.begin();

if (!mp.count(word)) mp.insert(make_pair(word, 1)); else mp[word]++; } fs.close(); // Traverse map and print all words whose count //is 1 for (map<string, int> :: iterator p = mp.begin(); p != mp.end(); p++)

Programming challenge description: Given a string comprising just of the characters (,),{,},[,] determine if it is well-formed o

nadezda [96]

Answer:

Employing Java language,

Explanation:

//for using stack data structure

import java.util.Stack;

//class definition

public class BracketMatch {

//function to find the string is well formed or not

public static boolean isWellFormed(String str) {

//variable to store the character value

char ch;

//check if the first character itself is the end of the brackets

if (str.charAt(0) == ')'||str.charAt(0) =='}'||str.charAt(0) ==']')

return false;

//creating a stack of character type

Stack<Character> stack = new Stack<Character>();

//iterating through the characters in string

for(int i=0; i < str.length(); i++) {

//storing the current character from the string in the variable

ch = str.charAt(i);

if(ch == '('||ch=='{'||ch=='[')

//if the character is starting of the brackets push it into stack

stack.push(ch);

else if(ch == ')')

//if it is closing bracket and the stack is empty then the string is not well formatted

if(stack.empty())

return false;

else if(stack.peek() == '(')

stack.pop();

else

return false;

else if(ch == '}')

if(stack.empty())

return false;

else if(stack.peek() == '{')

stack.pop();

else

return false;

}

//returning the stack content, if the string will be well formed the stack would be empty

//after all the operations

return stack.empty();

}

//main method

public static void main(String[] args) {

//calling function to find if the string is welll formatted or not

System.out.println(isWellFormed("{}"));

//calling function to find if the string is welll formatted or not

System.out.println(isWellFormed("([)]"));

python A pet shop wants to give a discount to its clients if they buy one or more pets. The discount is equal to 20 percent of t

Artyom0805 [142]

Answer:

The following are the program in the Python Programming Language.

#define function

def discount(prices, isPet, nItems):

# declare and initialize variables to 0

i = 0

cost = 0

pets = 0

item = 0

item_Cost = 0

#set the while loop

while(i < nItems):

#check the items of the variable

if isPet[i]:

#add and initialize in the cost

cost += prices[i]

#increament in the variable by 1

pets += 1

#otherwise

else:

#add and initialize in the item_Cost

item_Cost += prices[i]

#increament in the variable by 1

item += 1

#then increment in the variable by 1

i += 1

#check the pet is greater than equal to 1

#and item is greater than equal to 5

if(pets >= 1 and item >=5):

#then, print the message

print("You receive discount")

#set discount of the items

discount = 0.2 * item_Cost

# calculate bill after deducting discount

bill = cost + item_Cost - discount

#print the bill

print("Final Bill amount is", bill)

#otherwise

else:

#print the message

print("You do not receive any discount")

#calculate bill without deducting discount

bill = cost + item_Cost

#print the final bill

print("Final Bill amount is", bill)

#set empty list type variables

price = []

pet = []

#set the infinite loop

while True:

#get input from the user

sprice = int(input("Enter the price (-1 to quit): "))

#check that price is not equal to the -1

if(sprice != -1):

#add price in the list

price.append(sprice)

#ask for choice from the user

choice = input("Is it a pet (Y / N)? ")

#check the choice of the user is y or Y

if(choice == 'Y' or choice == 'y'):

# then, add in the pet

pet.append(True)

#otherwise

else:

#not add in the pet

pet.append(False)

print("")

#break the loop

else:

break

#declare variable that store the length

items = len(price)

#call and initialize the variable

discount(price, pet, items)

Output:

Enter the price (-1 to quit): 96

Is it a pet (Y / N)? y

Enter the price (-1 to quit): 69

Is it a pet (Y / N)? n

Enter the price (-1 to quit): 41

Is it a pet (Y / N)? n

Enter the price (-1 to quit): 52

Is it a pet (Y / N)? n

Enter the price (-1 to quit): 96

Is it a pet (Y / N)? n

Enter the price (-1 to quit): 74

Is it a pet (Y / N)? n

Enter the price (-1 to quit): -1

You receive discount

Final Bill amount is 361.6

Explanation:

The following are the description of the program.

Firstly, define the function 'discount()' and pass the arguments 'prices', 'isPet' and 'nItems' in its parameter.
Then, declare and initialize the variables 'i' to 0, 'item_Cost' to 0
, item to 0, 'cost' to 0 and 'pets' to 0.
Then, set the while loop to add the price of the items and the cost of the pets.
Set the if-else conditional statement to check the pet is greater than equal to 1 and the items are greater than equal to 5 then, set the discount and print the bill after deduction.
Otherwise, print the bill without deduction.
Finally, set two list type variable then, set the infinite while loop that gets input from the user and check that the variable is not equal to -1 then append the data in the list then again check the user input then append in pet otherwise not append in pet and break the loop. Then, set the variable that stores the length of the price and call the following function by passing arguments in its parameter.
