What is Cyclic Sort?

Cyclic sort is a sorting technique for arrays whose values fall in a known, contiguous range, typically 1 to n. Each element is swapped to the position matching its value, placing everything correctly in O(n) time and O(1) space — ideal as a building block for problems such as finding missing or duplicate numbers.
