Answer:
The program code is in explaination
Explanation:
Program code below.
def judge(auction,price):
"""
Function: Returns Name who auctioned very near to give price
Input :
auction : list of tuples
price : auction price
output: returns name of best auction amount holder
"""
diff = [] #storing differences between auctionist amount and price
count = 0
for each_pair in auction:
if each_pair[1]<=price:
diff.append(price-each_pair[1])
else:
count+=1
diff.append(each_pair[1])
if count == len(auction): #check for if no one have auctioned good amount
return None
else:
more_possibility_index = diff.index(min(diff)) #finding index of best amount from diff list
return auction[more_possibility_index][0]
auction = [('Alice',430),('Bob',538),('Carol',487),('David',550)]
price = 520
print(judge(auction,price))
I kept the output at the attachment.
Answer:
#include <iostream>
using namespace std;
int main() {
int k;
double d;
string s;
cin >> k >> d >> s;
cout << s << " " << d << " " << k << "\n" << k << " " << d << " " << s; }
Explanation:
k is int type variable that stores integer values.
d is double type variable that stores real number.
s is string type variable that stores word.
cin statement is used to take input from user. cin takes an integer, a real number and a word from user. The user first enters an integer value, then a real number and then a small word as input.
cout statement is used to display the output on the screen. cout displays the value of k, d and s which entered by user.
First the values of k, d and s are displayed in reverse order. This means the word is displayed first, then the real number and then the integer separated again by EXACTLY one space from each other. " " used to represent a single space.
Then next line \n is used to produce a new line.
So in the next line values of k, d and s are displayed in original order (the integer , the real, and the word), separated again by EXACTLY one space from each other.
The program along with the output is attached.
