Bucket Sorting Technique in Data Structure Using C

Bucket sort is simple algorithms technique. This sorting technique is also known as bin sort. In this sorting technique that works by separating an array elements into a number of buckets. Each bucket is then sorted individually, either using different sorting technique or by recursively applying the bin sorting algorithm. When we apply bucket sort algorithm then following points will be applied: 1. Set up an array of initially empty buckets. 2. Scatter Go over the original array, putting each object in its bucket. 3. Sort each non-empty bucket. 4. Gather: Visit the buckets in order and put all elements back into the original array. Lets see how it works by each element of the array is put in one of the N “buckets” as shown below figure: Step 1: 2 1 1 3 2 Bucket no. 1 Bucket no. 2 Bucket no. 3 Step 2: 1 1 3 2 Bucket no. 1 Bucket no. 2 Bucket no. 3 Step 3: 1 3 2 Bucket no. 1 Bucket no. 2 Bucket no. 3 Step 4: 3 2 Bucket no. 1 Bucket no. 2 Bucket no. 3 Step 5: 2 Bucket no. 1 Bucket no. 2 Bucket no. 3 At last all element now each element of array is in the proper bucket as shown below figure : Bucket no. 1 Bucket no. 2 Bucket no. 3 1 Bucket no. 1 Bucket no. 2 Bucket no. 3 At last all array elements are now sorted order. 1 1 2 2 3 Bucket sort algorithm works by main three points are as following: 1. Create N linked lists (buckets) to divide interval [0,N] into subintervals of size 1 2. Add each input element to appropriate bucket 3. Concatenate the buckets. Advantages of Bucket sort are as follow: 1. It is simple and easily implementation that works by partitioning an array into a number of buckets. 2. It is only efficient for large size lists. Disadvantages of Bucket sort are as follow: 1. You can know about all algorithms for this algorithm implement. 2. It is a complex algorithm and it’s not nearly as efficient as the merge and quick sorts.
