@Aditi: Form a max-heap of the first 100 numbers. Then as you read the remaining numbers, if a number is less than the root of the max-heap, replace the root with it and restore the heap condition. When you reach the end of the million numbers, the heap will contain the smallest 100 numbers.
If there are n numbers and you want the smallest k, this algorithm is O(n log k).
