Radix Sort

 

🚀 Radix Sort: The Fastest Sorting Algorithm for Large Numbers?

When it comes to sorting large numbers efficiently, Radix Sort is a game-changer! Unlike traditional comparison-based algorithms like QuickSort or MergeSort, Radix Sort groups numbers by their digits, processing them from the least significant to the most significant place.

🔹 How Radix Sort Works:

1️⃣ Find the maximum number to determine the number of digits.
2️⃣ Sort numbers based on each digit, from the least significant to the most significant, using a stable sorting algorithm like Counting Sort.
3️⃣ Repeat until all digits are processed.

⚡ Why Use Radix Sort?

Faster for large numbers (O(nk) time complexity, where n is the number of elements and k is the number of digits).
Avoids comparison-based sorting (great for cases with fixed-length numbers).
Stable sorting – maintains the relative order of equal elements.

❌ When Not to Use It?

❌ Takes up extra space for buckets.
❌ Slower for short numbers compared to QuickSort.

🔍 Use it when sorting long numbers, IDs, or large datasets with a fixed range!
