  • Because comparing with 1 is expensive (requires copying and decrementing), we instead use a modified version of the Collatz sequence - namely, we use the sequence where every number is one lower. This allows us to compare with 0 instead.
  • ```text

  • 要 While n (is non-zero)
  • ⓶增⓶ Increment the counter
  • ❶갠剩 Take mod 2

  • 不 Else
  • 增갰乘 Add 1 and multiply by 3
  • End if
  • 終 End while
  • 丟 Drop n, leaving only the counter
