My Javascript solution

function towerBreakers(n, m) {
    // Write your code here
    return (m === 1 || n%2 === 0) ? 2 : 1
}

If you are here because the discription doesn't match the results, you gotta consider that a tower can be reduced directly to 1. example:

2 towers of height 7

p1: 7 -> 1 (x=1 y=6 -> x divides y)

p2: 7 -> 1 (x=1 y=6 -> x divides y)

p1 loses

p2 wins, therefore returns p2

the description says that y should divide x but in reality x should divide y

Please fix that description

Solution that worked for me with an assumption that player 2 always mirrors player 1's moves:(if someone understands why we should assume that please explain)

if (m == 1) { return 2; }

    // If there are an odd number of towers, Player 1 wins
    // If there are an even number of towers, Player 2 wins
    return (n % 2 == 1) ? 1 : 2;

no need to tell you how awful this problem description was, they even gave a contradicting example with the description of the "rules",

"1 <= y < x where y EVENLY DIVIDES x" then proceeds to give an example about only 2 choices when m = 6, y =3 or y= 5 to leave 1, then how is 5 is a valid choice, thank you for your time but please respect our little brains
