Radix Sort
overall review score: 4.2
⭐⭐⭐⭐⭐
score is between 0 and 5
Radix sort is a non-comparative integer sorting algorithm that processes data by grouping keys based on individual digits or bits, starting from the least significant digit (LSD) or most significant digit (MSD). It efficiently sorts large sets of integers or strings by leveraging the positional properties of their elements, often achieving linear time complexity under certain conditions.
Key Features
- Non-comparative sorting algorithm
- Operates by processing digits or bits from least to most significant (or vice versa)
- Often implemented using counting sort as a subroutine
- Efficient for sorting large datasets with fixed-length keys
- Time complexity generally O(n·k), where n is the number of elements and k is the key length
Pros
- Highly efficient for large datasets with fixed-length keys
- Linear time complexity in ideal scenarios, outperforming comparison-based sorts like quicksort
- Stable sort, preserving the relative order of equal elements
- Simple to implement for specific use cases
Cons
- Less effective for data with variable-length keys or strings without modifications
- Requires additional space for counting buckets and auxiliary arrays
- Not suitable for all data types; primarily optimized for integers and fixed-length strings
- Performance can degrade if the key size (k) is large or not bounded
