In Q/KDB: /1 million random floats between 0 and 10 a:1000000?10.0; b:1000000?10.0; c:1000000?10.0; sum each flip (a;prev b;next c) /To do it in parallel sum peach flip (a;prev b;next c) Sometimes it is like living in a world where people refuse to use sheet music/clefs/bars and instead they read and write music by listing the notes, their frequencies and how long to play them for.
