**Changelog:**
+ (Sean) Clarified what to push and how to remove ``*.byte``
files.
+ (Sean) Initial version.
Time for a booster! 💊💪
Introduction 💁
For today's lab, you will complete Exercise 3.5 from Okasaki's book:
**Exercise 3.5** Define findMin directly rather than via a call to
``removeMinTree``.
Your will define this new function as ``findMinDirect`` in your
``Hwk_08/binomialheap.ml`` file.
Getting started 🐔
Perform the "getting started" step from Hwk_08. (If you have already done this
for Hwk_08, you are all set.)
Be productive 🤳
Open your ``Hwk_08/binomialheap.ml`` file. In your ``BinomialHeapSig``
signature, add your new function:
```
findMinDirect: t - elem
```
The function has the same type as ``findMin``. That is, it takes a binomial
heap as input and outputs an element.
Be direct 🎯
Now, implement ``findMinDirect`` in your ``BinomialHeap`` functor, defined as
follows: Given a binomial heap, output the minimum value element in the heap.
Your function must not call ``removeMinTree`` or ``findMin``.
Be confident 💩
Test your work by using the "putting it all together" step from Lab_13, and
adding the following line at the bottom of your file:
```
let m3 = BHI.findMinDirect h6
```
Notice that ``m3`` should evaluate the same as ``m2`` (namely, 20).
Compiling your code 🎪
Add this line at the top of your ``Hwk_08/binomialheap.ml`` file:
```
open Ordered
```
Then, run the following commands in order:
```
ocamlbuild ordered.byte
ocamlbuild binomialheap.byte
```
You should see no errors.
*Note: If you want to test your work again in the OCaml toplevel, you must
comment or remove the ``open Ordered`` line. But add it back in before pushing
your work to your repository.*
Turning in your work 🎰
Push your updated ``Hwk_08/binomialheap.ml`` file to your repository before the
due date.
Do not push ``ordered.byte`` or ``binomialheap.byte``. These are binary
executable files, and our main goal is to ensure that your code compiles
successfully. (You can even try running the command ./binomialheap.byte which
will appear to do nothing.)
If you accidentally committed and pushed these files, please do the following
from your ``Hwk_08`` directory in your repository:
```
git rm ordered.byte
git rm binomialheap.byte
```
Commit this change and pull and push as usual, before the due date.
Thank you and many apologies for any confusion. 🙇
