You are given a 3 × 3 Tic-tac-toe board stored as a two-dimensional array. Find out the winner of the game, or return ' ' if there is no winner.
TicTacToe = (board) => {
let winbits = [7,56,73,84,146,273,292,448];
board = Array.prototype.concat.apply([], board);
query = player => {
num = 0;
board.forEach((cell, i) => {
var i = (board.length-i)-1;
num += (cell === player)<<i;
});

Last active April 6, 2016 15:18
Given a string `s`, determine whether or not it is possible to rearrange the letters in the string to make a palindrome. (Post manual "uglify")
CanMakePalindrome = (s, b, o, t) => {
t = s.length % 2;
o = [...s].filter(l => {
b = s.split(l);
s = b.join``;
return (b.length - 1)%2;
});
return t ? (o.length === 1) : (o.length === 0);
