Day 55 Of 100DaysCode : More About Algorithm

Today is my day 55th of 100daysofcode and python learning. Like today I also continue to learned properties of SQL from datacamp.
Like ORDER BY, GROUP BY, HAVING, etc. Also learned more about algorithm from Coursera.

Python Code

Code to calculate maximum pairwise product.

def max_pairwise_product(numbers):
    n = len(numbers)
    max_product = 0
    for first in range(n):
        for second in range(first+1,n):
            max_product = max(max_product, numbers[first] * numbers[second])
    return max_product

input_n = int(input())
input_numbers = [int(x) for x in input().split()]
print(max_pairwise_product(input_numbers))

Output of the following code is,

3
5 6 9
54

input_n = int(input())
input_numbers = [int(x) for x in input().split()]

• input_n was not used.
• [int(x) for x in input().split()] is the same as list(map(int, input().split()))

To make use of input_n you would have to modify def max_pairwise_product(numbers): to add another parameter, say n as def max_pairwise_product(numbers, n): so that in the function body you'd remove n = len(numbers).

So you would add another parameter, n and remove the line, n = len(numbers)

Yes. Thank you for the suggestion.
