Median

Find the median of a stream of binary integers as fast as possible.

Input: 100 000 000 uint32 values in little-endian binary on STDIN (4 bytes each).

Output: The median value, printed as a decimal string. The median is defined as the element at index N/2 (i.e., a[50000000]) in the sorted array.
