I'm probably being extremely dumb right now, but for round 641, div2C, I literally had the right solution but I spend 1h30m trying to implement the last part (counting factors and then getting 2nd minimum one) but I couldn't do it w/o hashmaps or arraylists, which ofc MLE. Can anyone help me approach this last part (because the editorials used the first solution, but i used the second so i have nothing to go on)
