void quickSort(int A[], int n) { stack<pair<int, int>> stk; stk.push(make_pair(0, n-1)); while (!stk.empty()) { pair<int, int> p = stk.top(); stk.pop(); int r = rand() % (p.second-p.first+1) + p.first; swap(A[r], A[p.first]); int j = p.first; for...
Examples: Tree and graph traversals, divide-and-conquer algorithms like quicksort and mergesort, and problems involving backtracking like solving mazes or puzzles.IterationIterative solutions are generally more efficient in terms of memory and execution time and which involves simple repetition. For the...
We turn next to the discussion of the OpenMP version of two recursive examples: computation of the area under a curve and the parallel version of the quicksort algorithm. Consider first the recursive computation of the area under a curve. The algorithm is implemented as follows: if the range...
If the error is OS dependent, I may have to consider using a loop iterative process suggested by Jim Dempsey. I am using the latest IVF 12 update 3 compiler.To Intel people, I did not get any runtime error for this problem in release mode.Only upon debugging (after an unusual result)...
