quicksort fortran

Title Link: http://poj.org/problem?id=2299DescriptionIn this problem, you has to analyze a particular sorting algorithm. The algorithm processes a sequence of n distinct integers by swapping, adjacent sequence elements until the sequence is Sorted in ascending order. For the input sequence 9 1 0 5 4, Ultra-quicksort produces the output 0 1 4 5 9. Your task is to determine what many swap operations Ultra-

The answer is half ninety. After reading the quick sorting, I understand its idea and will implement its Code. However, is this the quicksort algorithm I need? Apparently not. Question 7-2: What if the elements in the array are the same? If a program is directly implemented using pseudo code, the time complexity is the square of n. The author provides an idea when a [p .. if the elements in R] are the same, the returned Q is (p + r)/2, which ensures t
