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 countAi by 1
• After all the input array is read, scan the count
  array, printing out a representation of sorted
  list.

Radix Sort

• Radix sort is generalization of bucket sort.
• 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
• .
