In the first line we initialize L₁, L₂, and L₃. We sort L₁ so like values will be adjacent.

Then we start looping by storing the first value encountered to the next element of list L₂.
In the next line we find the frequency of the value already stored in L₂ and is stored to the correspondent element in L₃. θ is increased by the frequency found minus 1 to pass to next number, but then incremented by 1 in the For loop.
We loop we reach the end of L₁.

And that's it. The output is put on L₂ and L₃ already sorted. Notice how well Ans is used for speed and size optimization.

When you are done using L₁, L₂, and L₃, you should [[TI-BASIC:Cleanup|clean them up]] at the end of your program.[[Category:TI-BASIC]]
