js版本选择排序

function selectionSort(array) {
for(var i = 0; i < array.length; i++) {
var smallestNumberIndex = i;
for(var j = i + 1; j < array.length; j++) {
if(array[j] < array[smallestNumberIndex]) {
smallestNumberIndex = j;
}
}

if(smallestNumberIndex != i) {
  var temp = array[i];
  array[i] = array[smallestNumberIndex];
  array[smallestNumberIndex] = temp;
}

}
return array;
