dst[:dst_n] += src[:src_n] << (4*hex_shift)

Signature¶

def add_shifted dst_n, src_n, dst, src, hex_shift @ do_inc, end { ... }

Complexity¶

  • Time: src_n(4@+12)   + 5@+1        // It's on average, see the note in hex.inc.

  • Space: src_n(2.5@+39) + (dst_n - hex_shift)(1.5@+13) + 4@+28

See the complexity glossary for what @, w, dw, dbit, n mean.

Requires init¶

The following must be initialised before this macro is invoked:
