// We need to find the (minPrct*size) smallest value and the (maxPrct*size) smallest value in data.
// We use a histogram based search for speed and to reduce memory usage.
// Memory usage of this method is histoSize * sizeof(uint32_t) * (t + 1) byte,
// where t is the number of threads and histoSize is in [1;65536].
// Processing time is O(n) where n is size of the input array.
// It scales well with multiple threads if the size of the input array is large.
// The current implementation is not guaranteed to work correctly if size > 2^32 (4294967296).
