it is broken in js :(

   const [_, length, rawArr] = input.split('\n');

const arr = rawArr.split(' ').sort((a, b) => a - b);


let mid = Math.floor(length / 2);

[arr[mid], arr[length - 1]] = [arr[length - 1], arr[mid]]

let left = mid + 1;
let right = length - 2;
while (left < right) {
    [arr[left], arr[right]] = [arr[right], arr[left]];
    left++;
    right--;
}

const str = arr.join(' ');
const strTrim = str.trim();


console.log(strTrim);
