Bucket Sort Given that, we have N integers in the range 0 to M-1
Maintain an array count of size M, which is initialized to zero. Thus, count has M cells (buckets). Read Ai Increment count[Ai] by 1 After all the input array is read, scan the count array, printing out a representation of sorted list. April 25, 2019

It uses several passes of bucket sort Perform the bucket sorts by “least significant digits” First sort by digit in units place Second sort by digit in tens place Third sort by digit in hundreds place ……. April 25, 2019
