Radix Sort | Radix Sort program in c
Radix sort is a non-comparative sorting algorithm that works by distributing elements into buckets based on their individual digits or characters. It processes the digits or characters from the least significant to the most significant. Radix sort can be applied to integers, strings, or other data types that can be represented in a positional numeral system.
The basic idea behind radix sort is to repeatedly sort elements based on each digit or character, starting from the rightmost position and moving towards the leftmost position. After sorting according to one digit or character, the elements are collected back into a single list and the process is repeated for the next digit or character until all positions have been considered.
Radix sort can be implemented using various methods, such as LSD (Least Significant Digit) or MSD (Most Significant Digit) approaches. LSD starts sorting from the rightmost digit, while MSD starts from the leftmost digit. The efficiency of radix sort depends on the range of values for each digit or character and the number of digits or characters in the input elements.
Overall, radix sort has linear time complexity under certain conditions and can be more efficient than some comparison-based sorting algorithms for specific types of data.
