We need to consider both ascending and descending order, then return the minimum swaps required. What's wrong as I get only 2/13 test cases passing def minimumSwaps(popularity): temp = [0] * (len(popularity) + 1) for pos, val in and so the total number of swaps needed to get to the ideal state is $1 + 2 + 2 + 5 = 10$. If an element is not in its In the example, you need only one swap: array[3] <--> array[6]. If you're just trying to find the minimum number of swaps needed, without actually sorting it, you're looking at some modification of the selection sort. You are allowed to swap any two elements.
