## Challenge Seed

<div id='js-seed'>

```js
// check if array is sorted
function isSorted(arr) {
  var check = (i) => (i == arr.length - 1) ? true : (arr[i] > arr[i + 1]) ? false : check(i + 1);
  return check(0);
}
// generate a randomly filled array
var array = new Array();
(function createArray(size = 5) {
  array.push(+(Math.random() * 100).toFixed(0));
  return (size > 1) ? createArray(size - 1) : undefined;
})(25);
var MinHeap = function() {
  // change code below this line
  // change code above this line
};
