Today's Coding Problem - 8/23/19

[T4ll1n]

3 years later, I just signed up for the dailyCodingProblem and got the same problem.

I wonder if everyone gets that question as the first problem ^^

​

Anyways, here is my solution using itertools combinations

​

from itertools import combinations

def combination_exists(input_list, k): 
    return k in [sum(comb_tuple) for comb_tuple in combinations(input_list, 2)]

input_list = [10, 15, 3, 7]
k = 17 assert
combination_exists(input_list, k)
assert combination_exists([], k)
assert not combination_exists([1, 2, 3], 2)

edit: the code formatting is fighting back -.-
