Radix sort

Radix Sort in C

Radix sort is a non-comparative integer sorting algorithm that sorts data with integer keys by grouping the keys by individual digits that share the same significant position and value. Here are the steps involved in implementing radix sort in C:

  1. Find the maximum number: Find the maximum number in the array to determine the number of digits in it. This will be used to determine the number of passes required for sorting.

  2. Initialize the buckets: Create 10 buckets to store the elements based on their digits (0 to 9).

  3. Perform the sorting: Iterate through each digit position, starting from the least significant digit to the most significant digit. For each digit position, perform the following steps:

  4. Place elements in buckets: Place each element in the respective bucket based on the value of the current digit being considered.

  5. Collect elements from buckets: After placing the elements in the buckets, collect the elements back from the buckets in the order they were placed.

  6. Repeat the process: Repeat the process for each digit position until all the digits have been considered.

  7. Output the sorted array: After the last pass, the array will be sorted in ascending order based on the radix (base) of the numbers.

Radix sort has a time complexity of O(n * k), where n is the number of elements and k is the number of digits in the largest number.
