  Radix Sort Basic Information

  Radix Sort is lower bound comparison based algorithm. It is a non-comparative integer sorting algorithm that sorts data with integer keys by grouping keys by individual digits which share some significant position and value. Radix sort is a linear time sorting algorithm that sort in O(n+k) time when elements are in range from 1 to k. The idea of Radix Sort is to do digit by digit sort starting from least significant digit to most significant digit. Radix sort uses counting sort as a subroutine to sort. Radix sort is generalization of bucket sort.

  Pseudo code for Bucket Sort:

  1. Create an array of [0..n-1] elements.
  2. Call Bucket Sort repeatedly on least to most significant digit of each element as the key.
  3. Return the sorted array.

  Example of Radix Sort:

  

  Space Auxiliary: O(n)
  Time Complexity: O(n)
