+# Day 23: Opening the Turing Lock
+Little Jane Marie just got her very first computer for Christmas from some unknown benefactor. It comes with 
+instructions and an example program, but the computer itself seems to be malfunctioning. She's curious what the program 
+does, and would like you to help her run it.
+
+The manual explains that the computer supports two [registers](https://en.wikipedia.org/wiki/Processor_register) and 
+six [instructions](https://en.wikipedia.org/wiki/Instruction_set) (truly, it goes on to remind the reader, a 
+state-of-the-art technology). The registers are named `a` and `b`, can hold any 
+[non-negative integer](https://en.wikipedia.org/wiki/Natural_number), and begin with a value of `0`. The instructions 
+are as follows:
+* `hlf r` sets register `r` to half its current value, then continues with the next instruction.
+* `tpl r` sets register `r` to triple its current value, then continues with the next instruction.
+* `inc r` **increments** register `r`, adding `1` to it, then continues with the next instruction.
+* `jmp offset` is a **jump**; it continues with the instruction `offset` away **relative to itself**.
+* `jie r, offset` is like `jmp`, but only jumps if register `r` is **even** ("jump if even").
+* `jio r, offset` is like `jmp`, but only jumps if register `r` is `1` ("jump if **one**", not odd).
+
+All three jump instructions work with an **offset** relative to that instruction. The offset is always written with a 
+prefix `+` or `-` to indicate the direction of the jump (forward or backward, respectively). For example, `jmp +1` 
+would simply continue with the next instruction, while `jmp +0` would continuously jump back to itself forever.
+
+The program exits when it tries to run an instruction beyond the ones defined.
+
+For example, this program sets `a` to `2`, because the `jio` instruction causes it to skip the `tpl` instruction:
+```
+inc a
+jio a, +2
+tpl a
+inc a
+```
+What is **the value in register `b`** when the program in your puzzle input is finished executing?
