Reduce Function Solution

This Python program is designed to calculate the product of a series of fractions. It uses the 'reduce' function from Python's 'functools' library to multiply the fractions together. The fractions are represented using the 'Fraction' class from the 'fractions' library.

Here is the Reduce Function Solution HackerRank solution using CodeRankGPT:

The solution works by first collecting a series of fractions from the user. These fractions are then passed to the 'product' function, which uses the 'reduce' function to multiply them together. The 'reduce' function works by applying a binary function (in this case, multiplication) to the first two items of the list, then to the result and the next item, and so on, until it has processed all items in the list. The result is then returned as a 'Fraction' object, and its numerator and denominator are printed out.


from fractions import Fraction
from functools import reduce

def product(fracs):
    t = Fraction(reduce(lambda x, y: x * y, fracs))
    return t.numerator, t.denominator

if __name__ == "__main__":
    fracs = []
    for _ in range(int(input())):
        fracs.append(Fraction(*map(int, input().split())))
    result = product(fracs)
    print(*result)
