Stable Counting Sort
Stable Counting Sort Stable counting sort extends counting sort by preserving the relative order of equal elements. This property is required in multi-pass algorithms such as radix sort. The algorithm uses prefix sums to compute exact output positions for each element. Problem Given an array $A$ of $n$ elements with integer keys in range $[0, k]$, produce a sorted array while preserving the relative order of elements with equal keys....
