### 2. Data Types (15 min)

Imagine that you're taking your favorite board game and turning it into a computer-based game. 

- [ ] Name of board game: ______

- [ ] Use the space below to categorize game data into each of the following data types. You should have a **minimum of two** pieces of data for each category. 

1. String data:
1. Integer and/or float data:
1. Boolean data:
1. Array data:
1. Hash or Object data:

### 3. Iteration (30 min)

- [ ] On a blank sheet of paper, create a diagram that shows how you understand iteration working. Be detailed and get creative! When you're done, take a photo of your diagram and post it in the Mod 0 channel on Slack. Your instructor(s) will provide feedback in a thread. _(If you're feeling extra fancy, feel free to create your diagram using software instead of pencil and paper)_

- [ ] Create a list below of **three real-life situations** where iteration is used. For each situation, explain why it would be an example of iteration.

### 4. Modify your Bash Profile (10 min)

- [ ] Watch [this video](https://drive.google.com/file/d/1s_CDBnxHSA0HDWldjosulthAvBi-C-d5/view?usp=sharing) and follow each step to modify your own bash profile. As mentioned in the video, you will need this snippet below:

```
# get current branch in git repo
function parse_git_branch() {
  BRANCH=`git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/\1/'`
  if [ ! "${BRANCH}" == "" ]
  then
    STAT=`parse_git_dirty`
    echo "[${BRANCH}${STAT}]"
  else
    echo ""
  fi
}

# get current status of git repo
function parse_git_dirty {
  status=`git status 2>&1 | tee`
  dirty=`echo -n "${status}" 2> /dev/null | grep "modified:" &> /dev/null; echo "$?"`
  untracked=`echo -n "${status}" 2> /dev/null | grep "Untracked files" &> /dev/null; echo "$?"`
  ahead=`echo -n "${status}" 2> /dev/null | grep "Your branch is ahead of" &> /dev/null; echo "$?"`
  newfile=`echo -n "${status}" 2> /dev/null | grep "new file:" &> /dev/null; echo "$?"`
  renamed=`echo -n "${status}" 2> /dev/null | grep "renamed:" &> /dev/null; echo "$?"`
  deleted=`echo -n "${status}" 2> /dev/null | grep "deleted:" &> /dev/null; echo "$?"`
  bits=''
  if [ "${renamed}" == "0" ]; then
    bits=">${bits}"
  fi
  if [ "${ahead}" == "0" ]; then
    bits="*${bits}"
  fi
  if [ "${newfile}" == "0" ]; then
    bits="+${bits}"
  fi
  if [ "${untracked}" == "0" ]; then
    bits="?${bits}"
  fi
  if [ "${deleted}" == "0" ]; then
    bits="x${bits}"
  fi
  if [ "${dirty}" == "0" ]; then
    bits="!${bits}"
  fi
  if [ ! "${bits}" == "" ]; then
    echo " ${bits}"
  else
    echo ""
  fi
}

export PS1="\u\w\`parse_git_branch\` "
```
