Three Way Quicksort
Three Way Quicksort Three way quicksort extends quicksort by handling duplicate keys efficiently. Instead of partitioning into two parts, it splits the array into three regions: elements less than the pivot elements equal to the pivot elements greater than the pivot This reduces unnecessary comparisons when many elements are equal. Problem Given an array $A$ of length $n$, reorder it such that: $$ A[0] \le A[1] \le \dots \le A[n-1]...
