# Problem Statement

Create a 1-bit wide, 256-to-1 multiplexer. The 256 inputs are all packed into a single 256-bit input vector. sel=0 should select in[0], sel=1 selects bits in[1], sel=2 selects bits in[2], etc.

> [!TIP]
> -  With this many options, a case statement isn't so useful.
> -  Vector indices can be variable, as long as the synthesizer can figure out that the width of the bits being selected is constant. In particular, selecting one bit out of a vector using a variable index will work.
