计数排序

// 计数排序(0,正整数) function countingSort(arr) { var len = arr.length; var maxNum = Math.max.apply({}, arr); var bucket = Array(maxNum + 1).fill(0); var newArr = []; for(var i = 0; i < len; i++) { bucket[arr[i]]++; } for(var j = 0; j <= maxNum; j++) { while(bucket[j] > 0) { newArr.push(j); bucket[j]--; } } return newArr; }
