We just need to maintain k largest elements seen so far. We can use a min-heap for this:
* Load the huge array by blocks that fit in memory
* If a number in the block is greater or equal to the min element in the heap or if the heap is empty, add it to the heap and remove the min element if the number of elements in the heap became k+1
* When we are done processing the array, the min element in the heap is the result
