Radix sort is efficient for sorting large numbers of integers or strings.Below is a list of all Buick cars and models that have come out so far.It is a stable sorting algorithm, meaning that elements with the same key value maintain their relative order in the sorted output.Radix sort has a linear time complexity, which makes it faster than comparison-based sorting algorithms such as quicksort and merge sort for large data sets.Also, Radix sort uses counting sort as a subroutine and counting sort takes extra space to sort numbers. The constant factors hidden in asymptotic notation are higher for Radix Sort and Quick-Sort uses hardware caches more effectively.
If we have log 2n bits for every digit, the running time of Radix appears to be better than Quick Sort for a wide range of input numbers. Is Radix Sort preferable to Comparison based sorting algorithms like Quick-Sort? This was then used by the operator to collect the cards which had the 1st row punched, followed by the 2nd row, and so on. The sorter was then programmed to sort the cards, depending upon which place the card had been punched. It was used in card sorting machines with 80 columns, and in each column, the machine could punch a hole only in 12 places.Alternatively, sorting the data three times using Radix sort first on the date, then on month, and finally on year could be used. You could compare two records on year, then on a tie on month and finally on the date.
For eg., you want to sort on three keys month, day and year. In a typical computer, which is a sequential random-access machine, where the records are keyed by multiple fields radix sort is used.In other words, we can sort an array of integers with a range from 1 to n c if the numbers are represented in base n (or every digit takes log 2(n) bits). What if we make the value of b larger? What should be the value of b to make the time complexity linear? If we set b as n, we get the time complexity as O(n). But it still doesn’t beat comparison-based sorting algorithms. In that case, the complexity becomes O(nLog b(n)). Which looks more than the time complexity of comparison-based sorting algorithms for a large k. So overall time complexity is O((n+b) * log b(k)). What is the value of d? If k is the maximum possible value, then d would be O(log b(k)). Radix Sort takes O(d*(n+b)) time where b is the base for representing numbers, for example, for the decimal system, b is 10.
