You could do in one loop, with two cursors :)

Go through the array twice. In the first run save the min and max, in the second run remove them. Both steps are O(N), so the entire algo is also O(N), it does not matter that the array is walked twice.

1. find max and min in first loop 2. In second loop following if element is min/max = simply increment a counter else a[i-counter] = a[i].
