Problem 59876. Out-of-Place Elements Count
Determine the number of elements in a list of integers that are not in their original order after sorting the list in ascending order.
For example, given the input vector [4, 2, 5, 1, 3], after sorting it becomes [1, 2, 3, 4, 5]. Comparing the sorted elements with the original elements:
- 1 is at position 4, so it's not in its original position.
- 2 is at position 2, so it's in its original position.
- 3 is at position 5, so it's not in its original position.
- 4 is at position 1, so it's not in its original position.
- 5 is at position 3, so it's not in its original position.
Therefore, there are 4 elements (1, 3, 4 and 5) that are not in their original order. So, the function returns 4.
