Join Raghavendra Dixit for an in-depth discussion in this video Radix sort, part of Introduction to Data Structures & Algorithms in Java.
- [Instructor] Now let's quickly understand…what the radix sort algorithm is;…but before that, what is a radix?…Well, in a number system, the radix or base…represents the number of unique digits, including zero,…that are used to represent the numbers in that system.…For example, in the decimal number system,…the radix or base is ten.…In the binary number system, the radix or base is two.…In case of radix sort algorithm,…we sort the numbers by the radix position.…
For example, in case of decimal number system, we would…first sort the numbers by digits in the ones' place.…Like in this example, if we sort the numbers just by digits…in the ones' place, this is how our array would look like.…Then we move to the next position, the tens' position,…and sort all the numbers again based on the digit…at the tens' position, so that 713…will come first, then 821, and so on.…
And then we sort the numbers…by digits in the hundreds' position;…and as you can see, all the numbers are sorted.…Now, this algorithm is also a linear time algorithm…
