We have n chips, where the position of the ith chip is position[i].
We need to move all the chips to the same position, In one step, we can change the position of the ith chip from position[i] to:
position[i] + 2 or position[i] - 2 with cost = 0.
position[i] + 1 or position[i] - 1 with cost = 1.
Return the minimum cost needed to move all the chips to the same position.

分别统计奇数位置和偶数位置的个数,相当于把所有奇数放一起,所有偶数的放一起,然后比较奇数的少还是偶数的少,将少的个数移到多的个数位置上去就可以了.

让我想起了小学时代被奥数支配的恐惧。
var minCostToMoveChips = function(position) {
let odd = 0, even = 0;
for(let i = 0; i < position.length; i++){
if(position[i] % 2 === 0){
even++;
}else{
odd++;
}
}
return Math.min(odd, even)
};
