Algorithm Details

Time:O(d×(n+k))

Space:O(n + k)

Stable:Yes

In-place:No

Type:Non-comparison

d = number of digits

n = number of elements

k = range of input (10 for decimal)

When to Use Radix Sort

✓Sorting integers with fixed number of digits
✓When n is large and d is small
✓Sorting strings of equal length
✓When stability is required
✗Floating-point numbers
✗Variable-length strings
✗When memory is severely limited

Real-world Applications

•Sorting large datasets of integers
•Database systems with numeric keys
•Sorting IP addresses
•Counting sort variations
•Suffix array construction

Key Characteristics

•Non-comparison based algorithm
•Works by processing individual digits
•Can outperform O(n log n) algorithms
•Uses counting sort as subroutine
