我一直在Objective-C(quicksort,mergesort,bubblesort)中实现不同的排序算法。但我还没有找到任何明确的Bucket Sort算法实现
我正在尝试在目标C中找到一个简单而有效的Bucket Sort算法实现。
答案 0 :(得分:1)
我最终完成了自己的工作,如果有人需要的话,这是我的实施:
- (NSArray*)bucketSort:(NSArray<NSNumber*> *)array buckets:(NSInteger)k {
// Initialize array of buckets
NSMutableArray<NSMutableArray*> *buckets = [NSMutableArray arrayWithCapacity:k];
for (int i=0; i < buckets.count; i++)
buckets[i] = [NSMutableArray new];
// Add elements to buckets
for (int i=0; i < buckets.count; i++) {
NSInteger index = k * array[i].floatValue; // Asuming "array" has values between 0 and 1
if (index < buckets.count) [buckets[index] addObject:array[i]];
}
NSMutableArray *sortedArray = [NSMutableArray new];
// Sort individual buckets
// Concatenate all sorted buckets in order
for (int i=0; i < buckets.count; i++) {
buckets[i] = [self quickSort:buckets[i]]; // Sorting algorithm like quicksort/mergesort/insertionsort
[sortedArray addObjectsFromArray:buckets[i]];
}
return sortedArray;
}
